  • How to determine magnitude of trigonometric function? C++

    - by seaworthy
    > if (((test>=0) && (test<=90)) || ((test>270) && (test<=360))){n_y=1;} > else {n_y=-1;} I need the magnitude of trigonometric function in order to determine the sign of the trigonometric function for an angle falling into a particular quadrant. My plan is to replace the code above with something equivalent. Here is what I want to do in pseudo-code. n_y = cos(test) / (magnitude of cos (test)); This will give me same thing. Abs() only takes integers. Any help is appreciated.

  • PHP Array Not Working in Function

    - by lemonpole
    Hello all. I'm currently experimenting with arrays in PHP, and I created a fake environment where a team's information will be displayed. $t1 = array ( "basicInfo" => array ( "The Sineps", "December 25, 2010", "lemonpole" ), "overallRecord" => array (0, 0, 0, 0), "overallSeasons" => array ( 1 => array (14, 0, 0), 2 => array (9, 5, 2), 3 => array (12, 4, 0), 4 => array (3, 11, 2) ), "games" => array ( "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />" ), "seasonHistory" => array ( "Season I", "Season II", "Season III", "Season IV" ), "divisions" => array ( "Open", "Main", "Main", "Invite" ) ); // Displays the seasons the team has been in along // with the record of each season. function seasonHistory() { // Make array variable local-scope. global $t1; // Count the number of seasons. $numrows = count($t1["seasonHistory"]); // Loop through all the variables until // it reaches the last entry made and display // each item seperately. for($v = 0; $v <= $numrows; $v++) { // Echo each season. echo "<tr><td>{$t1["games"][$v]}</td>"; echo "<td>{$t1["seasonHistory"][$v]}</td>"; echo "<td>{$t1["divisions"][$v]}</td></tr>"; } } I have tested several possible problems out and after narrowing them down I have come down to one conclusion and that is my function is not connecting to the array for some reason. I don't know what else to do because I thought making the array global would fix that problem. What works: I can echo $t1["games"][0] on the page I need it to display and it gives me the content. I tried echo $t1["games"][0] INSIDE the function and then calling the function and it doesn't display anything.

  • How with lambda function in MVC3

    - by doogdeb
    I have a model which contains view models for each view. This model is held in session and is initialised when application starts. I need to be able to populate a field from one view model with the value from another so have used a lambda function. Below is my model. I am using a lambda so that when I get Test2.MyProperty it will use the FunctionTestProperty to retrieve the value from Test1.TestProperty. public class Model { public Model() { Test1 = new Test1() Test2 = new Test2(FunctionTestProperty () => Test1.TestProperty) } } public class Test1 { public string TestProperty { get; set; } } public class Test2 { public Test2() : this (() => string.Empty) {} public Test2(Func<string> functionTestProperty) { FunctionTestProperty = functionTestProperty; } public Func<string> FunctionTestProperty { get; set; } public string MyProperty { get{ return FunctionTestProperty() ?? string.Empty; } } } This works perfectly when I first run the application and navigate from Test1 to Test2; I can see that when I get the value for MyProperty it calls back to Model constructor and retrieves the Test1.TestProperty value. However when I then submit the form (Test2) it calls the default constructor which sets it to string.Empty. So if I go back to Test1 and back to Test2 again it always then calls the Test2 default constructor. Does anyone know why this works when first running the application but not after the view is submitted, or if I have made an obvious mistake?

  • PHP - Use isset inside function not working..?

    - by pnichols
    I have a PHP script that when loaded, check first if it was loaded via a POST, if not if GET['id'] is a number. Now I know I could do this like this: if(isset($_GET['id']) AND isNum($_GET['id'])) { ... } function isNum($data) { $data = sanitize($data); if ( ctype_digit($data) ) { return true; } else { return false; } } But I would like to do it this way: if(isNum($_GET['id'])) { ... } function isNum($data) { if ( isset($data) ) { $data = sanitize($data); if ( ctype_digit($data) ) { return true; } else { return false; } } else { return false; } } When I try it this way, if $_GET['id'] isn't set, I get a warning of undefined index: id... It's like as soon as I put my $_GET['id'] within my function call, it sends a warning... Even though my function will check if that var is set or not... Is there another way to do what I want to do, or am I forced to always check isset then add my other requirements..??

  • What ways are there to edit a function in R?

    - by Tal Galili
    Let's say we have the following function: foo <- function(x) { line1 <- x line2 <- 0 line3 <- line1 + line2 return(line3) } And that we want to change the second line to be: line2 <- 2 How would you do that? One way is to use fix(foo) And change the function. Another way is to just write the function again. Is there another way? (Remember, the task was to change just the second line)

  • Function callers in C?

    - by thyrgle
    So I was wondering how they work. To explain what I mean by a "function caller" a good example of what I mean would be glutTimerFunc, it is able to take in a function as a parameter and call it even with it not knowing it is declared. How is it doing this?

  • When parsing XML with jquery, how can we pass the current node from within each() to another functio

    - by Johusa
    Say we have an XML document with many book nodes... When parsing XML with jquery, how can i pass the current node from each() iteration to another function that will do some stuff until something is reached and then go back to the previous function (passing along the current node from this function back to the first function)? Here something more descriptive (this is just an example out of my head, not accurate): function MyParser(x1,x2,dom) { // if i am called by anotherFunction(thisNode) proceed from the passed node dom.find('book').each(function() { var Letter = thisNode.find(author).charAt(0); if(x1 == Letter) { // print everything till the next letter (x2) anotherFunction(thisNode) } } } function anotherFunction(x2,thisNode) { //continue parsing here until you reached x2 //when x2 is reached, return to previous function passing again the current node }

  • class T in c++ (your definition)

    - by JohnWong
    The one advantage of using class T in c++ is to reduce the time to redefine data types in a function, if those data types are defined in other function, for example, in int main. template <class T> void showabs(T number) { if (number < 0 ) number = -number; cout << number << endl; return 0; } int main() { int num1 = -4; float num2 = -4.23f; showabs(num1); showabs(num2); return 0; } So in this case, without class T, for each data type, we have to add its corresponding data-type condition, that is, another set of if statement for int, and another one for float. Am I correct?

  • Can I use a method as a lambda?

    - by NewAlexandria
    I have an interface the defines a group of conditions. it is one of several such interfaces that will live with other models. These conditions will be called by a message queue handler to determine completeness of an alert. All the alert calls will be the same, and so I seek to DRY up the enqueue calls a bit, by abstracting the the conditions into their own methods (i question if methods is the right technique). I think that by doing this I will be able to test each of these conditions. class Loan module AlertTriggers def self.included(base) base.extend LifecycleScopeEnqueues # this isn't right Loan::AlertTriggers::LifecycleScopeEnqueues.instance_method.each do |cond| class << self def self.cond ::AlertHandler.enqueue_alerts( {:trigger => Loan.new}, cond ) end end end end end module LifecycleScopeEnqueues def student_awaiting_cosigner lambda { |interval, send_limit, excluding| excluding ||= '' Loan.awaiting_cosigner. where('loans.id not in (?)', excluding.map(&:id) ). joins(:petitions). where('petitions.updated_at > ?', interval.days.ago). where('petitions.updated_at <= ?', send_limit.days.ago) } end end I've considered alternatives, where each of these methods act like a scope. Down that road, I'm not sure how to have AlertHandler be the source of interval, send_limit, and excluding, which it passes to the block/proc when calling it.

  • Count, inner join

    - by Urosh
    I have two tables: DRIVER (Driver_Id,First name,Last name,...) PARTICIPANT IN CAR ACCIDENT (Participant_Id,Driver_Id-foreign key,responsibility-yes or no,...) Now, I need to find out which driver participated in accident where responsibility is 'YES', and how many times. I did this: Select Driver_ID, COUNT (Participant.Driver_ID)as 'Number of accidents' from Participant in car accident where responsibility='YES' group by Driver_ID order by COUNT (Participant.Driver_ID) desc But, I need to add drivers first and last name from the first table(using inner join, I suppose). I don't know how, because it is not contained in either an aggregate function or the GROUP BY clause. Please help :)

  • Are Objective-C function names stored in text?

    - by thyrgle
    I don't remember where I heard about it, (I think I was searching up on how selectors worked and it ended up not being exactly the same as a callback function) and I can't confirm it. But more importantly than that, is there a way I could get a list of the function names from another application?

  • is <p> a block-level or inline-level element?

    - by Andor
    hi there, i got a question when i come across the HTML 4.01 DTD: in the strict DTD, a element is defined as <!ELEMENT P - O (%inline;)* -- paragraph --> but somewhat i thought is a block-level, and all(maybe almost) user agents define as a block-level. so, i just wondering, is a block-level or inline-level element. thx.

  • trying to figure out how to bridge two virtual networks together and in turn bridge that to the internet for a virtual inline IDS/IPS system

    - by Tony robinson
    I'm trying to figure out how to bridge two vmware (server or workstation, workstation) or virtualbox networks together with a linux IDS/IPS system transparently inline between both the virtual networks. How do I accomplish this? I understand how to bridge to virtual networks together, but how to I make the linux virtual machine sit between them and force traffic to go across the transparent bridge? I would like to have something along the lines of: vmnet a various vms host-only network ---- inline linux box vmnet a boxes forced to go through here to get to the internet --- vmnet b network with internet access configured as either NAT or bridged -- internet I know that basically the linux box needs two virtual nics, one on vmnet a and vmnet b, but other than that, I don't know how to force all the traffic to go across the "transparent" bridging linux box on its way to the internet. Do vmnet a and b have to be the same ip network with the same default route? does vmnet a not have a default route and vmnet b have a default route? I've read in vmware forums that on the linux host you need to change permissions on the vmnet files for promiscuous mode? is this true? how do you configure this scenario on a windows box?

  • What are the useful UNIX functions that MS doesn't implement? And why? [closed]

    - by prosseek
    When programming with Python, I came across some functions that are not implemented on Windows. os.fork() may be one of them. UNIX came before WinNT, so the WinNT developers (most notably Dave Cutler) must knew about the features and functions of the UNIX. But, to me, it seems that MS didn't like UNIX so much that they mistakenly/intentionally skipped or distorted some of the useful UNIX functions/features; i.e. /abc/def in UNIX, \abc\def in Windows as an easy example. And when I read the Windows System Programming book, I felt uncomfortable as the Windows system functions seem nothing more than a tweak from UNIX. (I might be wrong.) What are those functions/features that MS OSes don't have, but UNIX origninated? Is there any reason for this? Do they just want to differentiate from UNIX world? Or do they think some of the UNIX functions are unnecessary? Is Windows a tweak from UNIX? Or, is there any great OS features that were invented in MS to make Windows better than UNIX?

  • Python - calculate multinomial probability density functions on large dataset?

    - by Seafoid
    Hi, I originally intended to use MATLAB to tackle this problem but the inbuilt functions has limitations that do not suit my goal. The same limitation occurs in NumPy. I have two tab-delimited files. The first is a file showing amino acid residue, frequency and count for an in-house database of protein structures, i.e. A 0.25 1 S 0.25 1 T 0.25 1 P 0.25 1 The second file consists of quadruplets of amino acids and the number of times they occur, i.e. ASTP 1 Note, there are 8,000 such quadruplets. Based on the background frequency of occurence of each amino acid and the count of quadruplets, I aim to calculate the multinomial probability density function for each quadruplet and subsequently use it as the expected value in a maximum likelihood calculation. The multinomial distribution is as follows: f(x|n, p) = n!/(x1!*x2!*...*xk!)*((p1^x1)*(p2^x2)*...*(pk^xk)) where x is the number of each of k outcomes in n trials with fixed probabilities p. n is 4 four in all cases in my calculation. I have created three functions to calculate this distribution. # functions for multinomial distribution def expected_quadruplets(x, y): expected = x*y return expected # calculates the probabilities of occurence raised to the number of occurrences def prod_prob(p1, a, p2, b, p3, c, p4, d): prob_prod = (pow(p1, a))*(pow(p2, b))*(pow(p3, c))*(pow(p4, d)) return prob_prod # factorial() and multinomial_coefficient() work in tandem to calculate C, the multinomial coefficient def factorial(n): if n <= 1: return 1 return n*factorial(n-1) def multinomial_coefficient(a, b, c, d): n = 24.0 multi_coeff = (n/(factorial(a) * factorial(b) * factorial(c) * factorial(d))) return multi_coeff The problem is how best to structure the data in order to tackle the calculation most efficiently, in a manner that I can read (you guys write some cryptic code :-)) and that will not create an overflow or runtime error. To data my data is represented as nested lists. amino_acids = [['A', '0.25', '1'], ['S', '0.25', '1'], ['T', '0.25', '1'], ['P', '0.25', '1']] quadruplets = [['ASTP', '1']] I initially intended calling these functions within a nested for loop but this resulted in runtime errors or overfloe errors. I know that I can reset the recursion limit but I would rather do this more elegantly. I had the following: for i in quadruplets: quad = i[0].split(' ') for j in amino_acids: for k in quadruplets: for v in k: if j[0] == v: multinomial_coefficient(int(j[2]), int(j[2]), int(j[2]), int(j[2])) I haven'te really gotten to how to incorporate the other functions yet. I think that my current nested list arrangement is sub optimal. I wish to compare the each letter within the string 'ASTP' with the first component of each sub list in amino_acids. Where a match exists, I wish to pass the appropriate numeric values to the functions using indices. Is their a better way? Can I append the appropriate numbers for each amino acid and quadruplet to a temporary data structure within a loop, pass this to the functions and clear it for the next iteration? Thanks, S :-)

  • How to include a PHP generated XML file into flash vars, while ALSO passing through the current php functions into it?

    - by Sam
    Hello Given situation: In webpage.php the flashscript is calling a flash script with a flashvar: the playlist file which is a PHP generated XML file: playlist.php, it does that well so long as there are no extra functions in there. Now, in that XML-format playlistfile there needs to be a special function, besides the usual echo("");, namely the very special echo __(""); function that is already declared in webpage.php which needs to do something with the paragraphs residing within that xml file. However, currently the retrieved file misses the function echo __();and says "no such function declared in that xml-format [playlist.php] file". The php functions that are currently included at the very top of webpage.php somehow do not pass-through-the necessary functions into the playlist file for it to recognise how to handle it, in order for that playlist to get those necessary functions working. Apparently these are not passed through automatically/properly when residing in the flashvars?? Cause the echo __(""); works fine when called within webpage.php or via a normal php include(""); if those functions are in a different php file. But not working from the playlist.php file. Any ideas why/what is going on here? I appreciate your clues for this prob +1. Thanks very much. WEBPAGE.PHP the webpage, has at the top an include with functions: <?php include (functions.php); ?> // function that know what to do with echo __("paragraph") <script language="JavaScript" type="text/javascript"> run( 'play', 'true', 'loop', 'true', 'flashvars', 'xmlFile=/incl/playlist.php', // <<<< !! 'wmode', 'transparent', 'allowScriptAccess','sameDomain', ); </script> <noscript> <object classid="blabla"> <param name="allowScriptAccess" value="sameDomain" /> <param name="movie" value="/movies/movie.swf" /> <param name="flashvars" value="xmlFile=/incl/playlist.php" /> // <<< !! <embed src="/movies/movies.swf" type="application/x-shockwave-flash"/> </object> </noscript> PLAYLIST.PHP The PHP generated XML file which is retrieved into the webpage as flash variable (see above) <?php echo ('<?xml version="1.0" encoding="UTF-8"?>'); echo ('<songs>'); echo ('<song version="1. "') . __("boom blue blow bell bowl") . ('/>'); echo ('<song version="2. "') . __("ball bail beam bike base") . ('/>'); echo ('</songs>'); ?>

  • What is the best approach for inline code comments?

    - by d1egoaz
    We are doing some refactoring to a 20 years old legacy codebase, and I'm having a discussion with my colleague about the comments format in the code (plsql, java). There is no a default format for comments, but in most cases people do something like this in the comment: // date (year, year-month, yyyy-mm-dd, dd/mm/yyyy), (author id, author name, author nickname) and comment the proposed format for future and past comments that I want is: // {yyyy-mm-dd}, unique_author_company_id, comment My colleague says that we only need the comment, and must reformat all past and future comments to this format: // comment My arguments: I say for maintenance reasons, it's important to know when and who did a change (even this information is in the SCM). The code is living, and for that reason has a history. Because without the change dates it's impossible to know when a change was introduced without open the SCM tool and search in the long object history. because the author is very important, a change of authors is more credible than a change of authory Agility reasons, no need to open and navigate through the SCM tool people would be more afraid to change something that someone did 15 years ago, than something that was recently created or changed. etc. My colleague's arguments: The history is in the SCM Developers must not be aware of the history of the code directly in the code Packages gets 15k lines long and unstructured comments make these packages harder to understand What do you think is the best approach? Or do you have a better approach to solve this problem?
