  • Replace empty cells with logical 0's before cell2mat in MATLAB

    - by Doresoom
    I've got a cell array of empty cells and ones that I want to convert to a logical array, where the empty cells are zeros. When I use cell2mat, the empty cells are ignored, and I end up with a matrix of solely 1's, with no reference to the previous index they held. Is there a way to perform this operation without using loops? Example code: for n=1:5 %generate sample cell array mycellarray{n}=1; end mycellarray{2}=[] %remove one value for testing Things I've tried: mylogicalarray=logical(cell2mat(mycellarray)); which results in [1,1,1,1], not [1,0,1,1,1]. for n=1:length(mycellarray) if isempty(mycellarray{n}) mycellarray{n}=0; end end mylogicalarray=logical(cell2mat(mycellarray)); which works, but uses loops.

  • delete pointer to 2d array c ++

    - by user1848054
    i have this pointer to 2d array of Robot class Robot ***rob; and this is here the code for the constructor !! and the program works fine !!! but now i am trying to build a destructor to delete this pointer !! and it keeps on crashing the program !! my question is , how to delete this pointer to 2d array of robots ? RobotsWorld::RobotsWorld(int x , int y) { X=x;Y=y; // returns the limitation of the matrix rob = new Robot**[x]; for(int i = 0; i < x; i++) { rob[i] = new Robot*[y]; for(int j = 0; j < y; j++) { rob[i][j] = NULL; } } }

  • How to make 7-Zip faster

    - by Matt
    I normally use WinRAR over 7-Zip simply because it's faster and only a little less efficient with compression. I did a few tests on different filetypes and sizes comparing the 7-Zip and WinRAR default settings on their normal compression and their best compression, and in a lot of cases WinRAR was 50% faster and in some it was actually 100% faster. But, I do like FOSS more. So here are my questions: Is there a way to make 7-Zip speed up? I'd like it to at least be on par with WinRAR's speed Is there a way to make recovery segments in 7-Zip like you can in WinRAR? I didn't see any, but I guess it could be a command line thing. I tested WinRAR and 7-Zip using the latest stable version of each (4-dot-something with 7-Zip). Is the 9.x beta release noticeably faster at compression? I'm talking about faster at a comparable setting in WinRAR, not just lowering to bare minimum compression. If it matters, I use a quad core Intel i7 720 (1.6 GHz)/(2.8 GHz) with 4 GB DDR3 RAM, and the 64-bit version of 7-Zip, and dual-boot Debian x64 5.0.4 and Windows 7 Home.

  • Typecast to an int in Octave/Matlab

    - by Leif Andersen
    I need to call the index of a matrix made using the linspace command, and based on somde data taken from an oscilloscope. Because of this, the data inputed is a double. However, I can't really call: Time[V0Found] where V0Found is something like 5.2 however, taking index 5 is close enough, so I need to drop the decimal. I used this equation to drop the decimal: V0FoundDec = V0Found - mod(V0Found,1) Time[V0FoundDec] However, eve though that drops the decimal, octave still complains about it. So, what can I do to typecast it to an int? Thank you.

  • Implementing PageRank using MapReduce

    - by Nick D.
    Hello, I'm trying to get my head around an issue with the theory of implementing the PageRank with MapReduce. I have the following simple scenario with three nodes: A B C. The adjacency matrix is here: A { B, C } B { A } The PageRank for B for example is equal to: (1-d)/N + d ( PR(A) / C(A) ) N = number of incoming links to B PR(A) = PageRank of incoming link A C(A) = number of outgoing links from page A I am fine with all the schematics and how the mapper and reducer would work but I cannot get my head around how at the time of calculation by the reducer, C(A) would be known. How will the reducer, when calculating the PageRank of B by aggregating the incoming links to B will know the number of outgoing links from each page. Does this require a lookup in some external data source?

  • Daubechies-4 Transform in MATLAB

    - by Myx
    Hello: I have a 4x4 matrix which I wish to decompose into 4 frequency bands (LL, HL, LH, HH where L=low, H=high) by using a one-level Daubechies-4 wavelet transform. As a result of the transform, each band should contain 2x2 coefficients. How can I do this in MATLAB? I know that MATLAB has dbaux and dbwavf functions. However, I'm not sure how to use them and I also don't have the wavelet toolbox. Any help is greatly appreciated. Thanks.

  • A definitive guide to Url Encoding in ASP .NET

    - by cbp
    I am starting to realise that there are about a bazillion different methods for encoding urls in .NET. I keep finding new ones. They all work slightly differently, but they all have essentially the same summary comments. Does anyone have a definitive matrix that shows the exact differences between the following methods: HttpUtility.UrlEncode HttpUtility.UrlPathEncode Server.UrlEncode Uri.EscapeUriString Uri.EscapeDataString ... are they any more? Also it would be good to match these up with use-cases e.g.: Urls in href attributes of a tags Urls to be displayed to the user in HTML Urls as querystring values (i.e. to be sent in GET requests) Urls to be sent in POST requests etc

  • Metric 3d reconstruction

    - by srand
    I'm trying to reconstruct 3D points from 2D image correspondences. My camera is calibrated. The test images are of a checkered cube and correspondences are hand picked. Radial distortion is removed. After triangulation the construction seems to be wrong however. The X and Y values seem to be correct, but the Z values are about the same and do not differentiate along the cube. The 3D points look like as if the points were flattened along the Z-axis. What is going wrong in the Z values? Do the points need to be normalized or changed from image coordinates at any point, say before the fundamental matrix is computed? (If this is too vague I can explain my general process or elaborate on parts)

  • how to build an accumulator array in matlab

    - by schwiz
    I'm very new to matlab so sorry if this is a dumb question. I have to following matrices: im = imread('image.jpg'); %<370x366 double> [y,x] = find(im); %x & y both <1280x1 double> theta; %<370x366 double> computed from gradient of image I can currently plot points one at a time like this: plot(x(502) + 120*cos(theta(y(502),x(502))),y(502) + 120*sin(theta(y(502),x(502))),'*b'); But what I want to do is some how increment an accumulator array, something like this: acc = zeros(size(im)); acc(y,x) = acc(x + 120*cos(theta(y,x)),y + 120*sin(theta(y,x)),'*b')) + 1; It would be nice if the 120 could actually be another matrix containing different radius values as well.

  • Windows service runs file locally but not on server

    - by Ben
    I created a simple Windows service in dot net which runs a file. When I run the service locally I see the file running in the task manager just fine. However, when I run the service on the server it won't run the file. I've checked the path to the file which is fine. I also checked the permissions on the folder and file, and they fine as well. Also there are no exceptions happening. Below is the code used to launch the process which runs the file. I posted this first on stack overflow, and some people were thinking this is a config issue, so I moved it here. Any ideas? try { // TODO: Add code here to start your service. eventLog1.WriteEntry("VirtualCameraService started"); // Create An instance of the Process class responsible for starting the newly process. System.Diagnostics.Process process1 = new System.Diagnostics.Process(); // Set the directory where the file resides process1.StartInfo.WorkingDirectory = "C:\\VirtualCameraServiceSetup\\"; // Set the filename name of the file to be opened process1.StartInfo.FileName = "VirtualCameraServiceProject.avc"; // Start the process process1.Start(); } catch (Exception ex) { eventLog1.WriteEntry("VirtualCameraService exception - " + ex.InnerException); }

  • R heatmaps - non-text labels?

    - by Carl
    I am making a heatmap plot; currently the axes are labeled by index number. However, the index number corresponds to a series of 1/0s, which my group typically represents with a row of filled(1) or unfilled(0) boxes (think chessboard, though not strictly alternating colors). I'd like to use that representation instead of the index numbers. Any suggestions? I've considered simply making the labels as a plot, and positioning that adjacent to the heatmap, but I'm not finding a convenient way to do that either. I will also appreciate answers that are more generically applicable. edit - current code: map <- data.matrix(read.csv("./heatmap.out", header=F, sep=" ")) # ...some clean-up p<-heatmap(map, Rowv=NA, Colv=NA, col=grey(10:0 / 10)) this simply labels the heatmap rows/cols by index number. heatmap.out is raw numeric data.

    - by agazerboy
    Hi All, I asked a question before but duffymo said it is not clear so i am going to post it again here. I am using Jama api for SVD calculation. I know very well about jama and SVD. Jama does not work if your column are more than rows. I have this situation. What should I do?? any help? I can't transpose the matrix too as it can produce wrong results. Thanks. P.S: I am calculating LSI with the help of jama. I am going like column(docs) and rows ( terms )

  • Are stack based arrays possible in C#?

    - by Bob
    Let's say, hypothetically (read: I don't think I actually need this, but I am curious as the idea popped into my head), one wanted an array of memory set aside locally on the stack, not on the heap. For instance, something like this: private void someFunction() { int[20] stackArray; //C style; I know the size and it's set in stone } I'm guessing the answer is no. All I've been able to find is heap based arrays. If someone were to need this, would there be any workarounds? Is there any way to set aside a certain amount of sequential memory in a "value type" way? Or are structs with named parameters the only way (like the way the Matrix struct in XNA has 16 named parameters (M11-M44))?

  • Sudoku solver evaluation function

    - by Rich
    Hi, So I'm trying to write a simple genetic algorithm for solving a sudoku (not the most efficient way, I know, but it's just to practice evolutionary algorithms). I'm having some problems coming up with an efficient evaluation function to test if the puzzle is solved or not and how many errors there are. My first instinct would be to check if each row and column of the matrix (doing it in octave, which is similar to matlab) have unique elements by ordering them, checking for duplicates and then putting them back the way they were, which seems long winded. Any thoughts? Sorry if this has been asked before...

  • Why I am getting "Problem loading the page" after enabling HTTPS for Apache on Windows 7?

  • How to simply remove everything from a directory on Linux

    - by Tometzky
    How to simply remove everything from a current or specified directory on Linux? Several approaches: rm -fr * rm -fr dirname/* Does not work — it will leave hidden files — the one's that start with a dot, and files starting with a dash in current dir, and will not work with too many files rm -fr -- * rm -fr -- dirname/* Does not work — it will leave hidden files and will not work with too many files rm -fr -- * .* rm -fr -- dirname/* dirname/.* Don't try this — it will also remove a parent directory, because ".." also starts with a "." rm -fr * .??* rm -fr dirname/* dirname/.??* Does not work — it will leave files like ".a", ".b" etc., and will not work with too many files find -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr find dirname -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr As far as I know correct but not simple. find -delete find dirname -delete AFAIK correct for current directory, but used with specified directory will delete that directory also. find -mindepth 1 -delete find dirname -mindeph 1 -delete AFAIK correct, but is it the simplest way?

  • Continuous Integration or Publishing System

    - by Chris M
    I've been testing Hudson for a few days now and for PHP projects it seems ok; What I need though is a system that will allow me to publish an SVN tag to an FTP folder without adding a pile of rubbish on the end; hudson gets overexcited and adds a pile of folders to the export. Are their any other decent systems; it needs to be simple to use as this will eventually fall under the control of 'admins' in order to meet sox compliance (aka the man with the gun cant pull the trigger). Basic Requirements: Must be free and downloadable to a server (FTP's internal only here) Needs to be able to interact with SVN Needs to be able to publish to FTP Needs matrix login permissions (or AD if its something that can go on IIS) Needs to be auditable (logging) Tell me if im not being clear enough here; thanks.

  • store/load numpy array from binary files

    - by Javier
    Dear all, I would like to store and load numpy arrays from binary files. For that purposes, I created two small functions. Each binary file should contain the dimensionality of the given matrix. def saveArrayToFile(data, fileName): with open(fileName, 'w') as file: a = array.array('f') nSamples, ndim = data.shape a.extend([nSamples, ndim]) # write number of elements and dimensions a.fromstring(data.tostring()) a.tofile(file) def readArrayFromFile(fileName): _featDesc = np.fromfile(fileName, 'f') _ndesc = int(_featDesc[0]) _ndim = int(_featDesc[1]) _featDesc = _featDesc[2:] _featDesc = _featDesc.reshape([_ndesc, _ndim]) return _featDesc, _ndesc, _ndim An example on how to use the functions is: myarr=np.array([[7, 4],[3, 9],[1, 3]]) saveArrayToFile(myarr,'myfile.txt') _featDesc, _ndesc, _ndim = readArrayFromFile('myfile.txt') However, an error message of 'ValueError: total size of new array must be unchanged' is shown. My arrays can be of size MxN and MxM. Any suggestions are more than welcomed. I think the problem might be in the saveArrayToFile function. Best wishes, Javier

  • width of a frustum at a given distance from the near plane

    - by structolite
    I'm using CML to manage the 3D math in an OpenGL-based interface project I'm making for work. I need to know the width of the viewing frustum at a given distance from the eye point, which is kept as a part of a 4x4 matrix that represents the camera. My goal is to position gui objects along the apparent edge of the viewport, but at some distance into the screen from the near clipping plane. CML has a function to extract the planes of the frustum, giving them back in Ax + By + Cz + D = 0 form. This frustum is perpendicular to the camera, which isn't necessarily aligned with the z axis of the perspective projection. I'd like to extract x and z coordinates so as to pin graphical elements to the sides of the screen at different distances from the camera. What is the best way to go about doing it? Thanks!

  • cmake, gcc, cuda and -m32 wtf

    - by Nils
    Hi all I figured out that CUDA does not work in 64bit mode on my mac (or couldn't get it running so far). Therefore I decided to compile everything for 32bit. I use cmake 2.8 and added the following options add_definitions(-Wall -m32) set(CUDA_64_BIT_DEVICE_CODE OFF) set(CMAKE_MODULE_LINKER_FLAGS -m32) However when it tries to link it it does something like this: /usr/bin/c++ -mmacosx-version-min=10.6 -Wl,-search_paths_first -headerpad_max_install_names CMakeFiles/SimpleTestsCUDA.dir/BlockMatrix.cpp.o CMakeFiles/SimpleTestsCUDA.dir/Matrix.cpp.o ./SimpleTestsCUDA_generated_SimpleTests.cu.o ./SimpleTestsCUDA_generated_BlockMatrix.cu.o -o SimpleTestsCUDA /usr/local/cuda/lib/libcudart.dylib /usr/local/cuda/lib/libcuda.dylib Which fails with a lot of "file is not of required architecture" warnings from ld. Now if I add manually -m32 to the command above it works. However I have no idea how to teach cmake to add -m32 to every gcc (or ld) invocation. So far it does it for nvcc and gcc, but not for linking..

  • How to simulate browser form POST method using PHP/cURL

    - by user283266
    I'm trying to simulate browser with POST method using PHP/cURL. When I looked at that live Http header it shows Content-Type: multipart/form-data. I checked on the internet where it was suggested that cURL will send multipart/form-data when a custom headers is specified to Content-Type: multipart/form-data. $headers = array( 'Content-Type' => 'multipart/form-data; boundary='.$boundary ); This didn't work for me either when I print_r(curl_getinfo()) it showed [content_type] => text/html; charset=UTF-8 Which means cURL sent a default headers I also read that sending/uploading a file with cURL will cause data to be send as multipart/form-data. I created a file which curl uploaded but again when I ran curl_getinfo I got [content_type] => text/html; charset=UTF-8 $data_array = array("field" => "@c:\file_location.txt"); I also tried to read a file content so that the only thing sent would be content NOT ATTACHED FILE but this didn't work for me curl_getinfo shows [content_type] => text/html; charset=UTF-8. $data_array = array("field" => "<c:\file_location.txt"); // note @ replaced with < Do I miss somthing here?

  • VC7.1 C1204 internal compiler error

    - by Nathan Ernst
    I'm working on modifying Firaxis' Civilization 4 core game DLL. The host application is built using VC7, hence the constraint (source not provided for the host EXE). I've been working on rewriting a large chunk of the code (focusing on low-hanging performance issues & memory leaks). I recently ran into an internal compiler error when trying to mod the code to use an array class instead of dynamically allocated 2-d arrays, I was going to use matrices from the boost lib (Civ4 is already using boost, so why not?). Basically, the issue comes down to: if I include "boost/numeric/ublas/matrix.hpp", I run into an internal compiler error C1204. MSDN has this to say: MSDN C1204 KB has this to say: KB 883655 So, I'm curious, is it possible to solve this error without a KB/SP being applied and dramatically reducing the complexity of the code? Additionally, as VC7 is no longer "supported", does anyone have a valid (supported) link for a VC7 service pack?

  • unevenly centered subplots in matplotlib in Python?

    - by user248237
    I am plotting a simple pair of subplots in matplotlib that are for some reason unevenly centered. I plot them as follows: plt.figure() # first subplot s1 = plt.subplot(2, 1, 1) plt.bar([1, 2, 3], [4, 5, 6]) # second subplot s2 = plt.subplot(2, 1, 2) plt.pcolor(rand(5,5)) # add colorbar plt.colorbar() # square axes axes_square(s1) axes_square(s2) where axes_square is simply: def axes_square(plot_handle): plot_handle.axes.set_aspect(1/plot_handle.axes.get_data_ratio()) The plot I get is attached. The top and bottom plots are unevenly centered. I'd like their yaxis to be aligned and their boxes to be aligned. If I remove the plt.colorbar() call, the plots become centered. How can I have the plots centered while the colorbar of pcolor is still shown? I want the axes to be centered and have the colorbar be outside of that alignment, either to the left or to the right of the pcolor matrix. image of plots link thanks.

  • Network problems with Ubuntu on VMware

    - by svick
    I'm running Ubuntu 10.04 inside VMware Player running under Windows Vista and I can't connect to the internet or the host computer from the Ubuntu. I have set all the VMware services to “manual” (like VMware DHCP Service), but starting them manually doesn't help. In VMware, the network seems to work (there is a green dot beside the network icon) and I have tried both Bridged and NAT settings. ifconfig doesn't show the eth1 interface, unless I give it as a parameter (or use -a). I think this means that Ubuntu thinks that the network isn't connected at all. How do I fix this? ifconvadmin@ubu1004:~$ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:56 errors:0 dropped:0 overruns:0 frame:0 TX packets:56 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4192 (4.1 KB) TX bytes:4192 (4.1 KB) vadmin@ubu1004:~$ ifconfig eth1 eth1 Link encap:Ethernet HWaddr 00:0c:29:2d:a0:6f BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:18 Base address:0x2000
