You could increase the Java Heap size as follows:
Windows:File->Preferences->General->Java heap space
Mac: MATLAB->Prefernces->General-> Java Heap Memory
Move the slider to maximum available Java Heap size and see if you still get the error
USe save or matfile to save your workspace
doc save
doc matfile

Thank you for your replay,
Could you please help me in finding the location:
Windows:File->Preferences->General->Java heap space
I am using windows 7, but could not find the folder File. Do you mean its in the MATLAB folder, there is no such folder as well?
All the best

I am using Matlab R 2008a, when I used the commands in the blog I got this message when running my program?

How are you saving the workspace? If you are saving variables to MAT-files, then consider using MATFILE command. It allows saving variable partially - using less memory in the process.
