Could you please help me with this!

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

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.

save('filename','A','-append') use this code
this may be useful for you.
