25 Mar 2014 ScreenCapture - get a screen-capture of a figure frame or component ScreenCapture gets a screen-capture of any Matlab GUI handle, or specified screen area rectangle Author: Yair Altman

screencapture(axesHandle,'target','filename.jpg') seems to save an image that's all black. The same thing happens if I give the gcf handle as an input.

The axes is in a gui with many other axes. I use guy layout -toolbox to position everything if that matters anything. I also use openGL renderer as I need transparency but I tried painters with similar results.

If I simply call screencapture() I get the Mouse click -prompt, but when I press ok the prompt and my gui become unselectable. If i press the Matlab-icon in my windows7 toolbar I see a new blank Matlab figure named 'Figure2' in the preview but I can't select it. I can still close it from the red cross and after that the prompt and my gui become selectable once again but no figure is saved of course.

What am I doing wrong?

21 Mar 2014 GUI Layout Toolbox Layout management objects for MATLAB GUIs Author: Ben Tordoff

Thanks for the great toolbox!

I use parallel toolbox with my gui when I open matlabpool within the gui and use parfor I get the following warnings:

Warning: com.mathworks.hg.peer.HG1FigurePeer@36300ca7 is not serializable
Warning: Could not deserialize object: java.io.InvalidClassException:
com.mathworks.hg.peer.FigureFrameProxy$FigureFrame; no valid constructor/n

Warning: The following error was caught while executing 'uiextras.Container'
class destructor:
Operands to the || and && operators must be convertible to logical scalar
> In remoteParallelFunction at 49

Should I be worried or can I just suppress these warnings? Everything seems to be working just fine though.

Thanks for the nice submission.

Add the possibility to give z-coordinates as well to produce 3d braces and I'll upgrade to 5 stars.

23 Feb 2012 Sparse sub access This package allows to retrieve and assign values of sparse matrix in one shot. Author: Bruno Luong

For more confusion, matlab version 2010a didn't crash in the example above. The 2011b on the otherhand, did.

This fantastics submission seems to have sort of a bug. I accidentally did the followin: B = setsparse(A,inf,inf,1).
This didn't result in a problem before my function ended and tried to clear the variable B. I know that this is strictly the user's problem but a single check if the indexes are suitable could be useful for other unfortunate fools...
