Download it again. If this does not help, post any details: Operating System, error log, ... Send these details to MathWorks using the "Contact Us" link on this page.

Hi Jan, I really appreciate the answers on matlab forum. Here I suffered a similar problem with the link docked figures, but I don't know how to add comments there. Could you please provide some suggestions: If there are many figures in the main window, how to change the width of each figure automatically so that the figures can fit different size controls?

Thanks a lot!

[Jan]

I do not understand, what you are asking for. Please post more details of your problem.

You can post comments in the other thread exactly like you do it here.

I'm sorrry for the unclear description. I have a program writed like this:

desktop = com.mathworks.mde.desk.MLDesktop.getInstance;

myGroup = desktop.addGroup('myGroup');

desktop.setGroupDocked('myGroup', 0);

myDim = java.awt.Dimension(4, 2); % 4 columns, 2 rows

% 1: Maximized, 2: Tiled, 3: Floating

desktop.setDocumentArrangement('myGroup', 2, myDim)

......

And my question is: How to set the width of each panel in the capture automatically?(Each panel takes a half as default)

This error can occur when MATLAB get's corrupted during the installation process.

To resolve this issue, disable any security software or allow exceptions for the MATLAB application and then perform an clean installation of MATLAB.

How do I perform a clean installation of MATLAB on a Windows system?

If the issue still persists after performing a clean installation, obtain the crash logs and contact MathWorks support.

How do I locate the crash dump files generated by MATLAB?
