  • Evaluating and graphing functions in Matlab

    - by thiol3
    New to programming, I am trying to graph the following Gaussian function in Matlab (should graph in 3 dimensions) but am making some mistakes somewhere. What is wrong? sigma = 1 for i = 1:20 for j = 1:20 z(i,j) = (1/(2*pi*sigma^2))*exp(-(i^2+j^2)/(2*sigma^2)); end end surf(z)

  • Has anyone had trouble with Intellisense in Visual Studio when using UltraVNC?

    - by mullala
    Hi, a colleague and I are trying pair programming for the first time. We both remote into a development machine; I'm using RemoteDesktop and my colleague is using UltraVNC. This works great except that he can't see the Intellisense dropdown in Visual Studio 2008. According to online posts, this may be something to do with DirectDraw, but I don't see much by way of a workaround. Has anyone else experienced this? Thanks, Andrew

  • Best solution for a windows service with constant running threads in C# 4.0

    - by dagda1
    Hi, I want to create a windows service that will create x number of threads that wake up every x number of minutes and do some work. I think the task scheduling or parallel framework is a bad fit for this type of work as it is best suited for work that starts, completes and finishes rather than is constant. Should I look at utilising a thread pool for this approach or does anyone have any advice for a good solution? Thanks Paul

  • How to uncheck header checkbox in GridView when sorting and paging?

    - by OutOFTouch
    Hi, I followed this article and it works great except when paging or sorting the HeaderCheckBox is still checked. How and where should this be unchecked? I think it would be best to uncheck it in the control itself, but I am not having any luck even getting a reference to it using this code: protected override void OnSorted(EventArgs e) { base.OnSorted(e); if (AutoGenerateCheckBoxColumn) { CheckBox cb = (CheckBox) HeaderRow.FindControl(String.Format(HeaderCheckBoxId, ClientID)); if(cb != null) { cb.Checked = false; } } } Thanks

  • URL Controller Mapping Strategies (PHP)

    - by sunwukung
    This is kind of an academic question, so feel free to exit now. I've had a dig through Stack for threads pertaining to URL/Controller mapping in MVC frameworks - in particular this one: http://stackoverflow.com/questions/125677/php-application-url-routing So far, I can ascertain two practices: 1: dynamic mapping through parsing the URL string (exploded on '/') 2: pattern matching matching url to config file containing available routes I wanted to get some feedback (or links to some other threads/articles) from folks regarding their views on how best to approach this task.

  • How to filter a list in J?

    - by Gregory Higley
    I'm currently learning the fascinating J programming language, but one thing I have not been able to figure out is how to filter a list. Suppose I have the arbitrary list 3 2 2 7 7 2 9 and I want to remove the 2s but leave everything else unchanged, i.e., my result would be 3 7 7 9. How on earth do I do this?
