Hide Matlab IDE menu bar
I'd like to hide the Matlab IDE menu bar, i.e. the bar at the top that has "file", "edit", "debug", etc, to save screen realestate. The following code almost does it: I = com.mathworks.mde.desk.MLDesktop.getInstance I.getMainFrame.getJMenuBar.setVisible(0) except that the bar reappears whenever you click on the ... 25 Jun 2010 03:20

random sampling of rows
Hi guys, I have the following matrix: X = [ 1 2 3; 4 5 6; 7 8 9] In matlab it looks like this: X = [ 1 2 3; 4 5 6; 7 8 9] X = 1 2 3 4 5 6 7 8 9 However, if I want to get X to output with randomly sampled rows for example,: X = 4 5 6 ... 22 Jun 2010 23:44

radio buttons and popup menus
Hi everyone Im new using the GUI function in MATLAB. I'm trying to develop an application using a popup menu to perform Sobel, Roberts or Gaussian edge detection and apply it to an image. The value chosen in the popup menu will be set into a variable B, but I have this problem: I does not work. I can't set directly th... 22 Jun 2010 20:27

Real-Time Color Tracking Particle Filter
I'm trying to implement a real-time color tracking particle filter. The filter works non real-time by using color histogram matching that checks each pixel. However, this will not work in real-time. How do I get measurements without searching each pixel? Also, I do not want to just search some subset, but I am lo... 22 Jun 2010 18:15

Follow the contour line
I am trying to follow a contour line with the matlab built-in function contourc: C = contourc(x_vec,y_vec,z,[value,value]) The returned matrix size and grids are chosen automatically, which is not what I want. The source code for this function does not come along with matlab. I am wondering if it's possible to ge... 23 Jul 2010 09:10

Graphing
Is there a way to use the gname function with specific cases on a figure with subplots. ie : gname(dates) on a subplot of (1,2,2) dimensions. Note that both graphs plot different series but the dates (i.e. cases) are consistent across either graphs. Thank You for any insight. Atilio ... 22 Jun 2010 19:21

Best way to share data between GUIDE m-file & Level-2 C-MEX s-function?
Update: there is a very straightforward way to pass data between an m-file and a C-MEX s-function: Within my gui’s m-file code, I use assignin(‘base’, varName, handles.VarName) and evalin(‘base’,’VarName’) calls to pass variables to and get variables from the Matlab workspac... 22 Jun 2010 17:08

Synchronizing components of xPC Target system
Hi, Ramon, Sorry for the delay in this reply. I wish it were possible to subscribe to these threads, so that we could be updated by email! I didn’t see your post until just now. That is the question now, how to make the simulation to start from a simulation that is stopped while in xptarget? I'm how can... 22 Jun 2010 18:15
