Increase Memory Available for MATLAB

I need more memory in MATLAB. Do you know how I can increase Memory Available for MATLAB. I'm using Windows XP x32 with Matlab R2010b. Thank you in advance.

Answer 1

[Sean de Wolski]

The easy way would be to buy a new computer with 64bit OS and 64bit MATLAB.

[SARAH ZAVAREH]

Good idea ;)

This is the most powerful solution. While the other tricks can increase the memory up to about 3GB, the 64 bit version can process 8TB in theory. Voted +1.

Some tips at Resolving "Out of Memory" Errors.

[SARAH ZAVAREH]

Yes I saw it. But I'm interested to know how I can increase memory available for matlab. I didn't find it there.

Then look at the sections "Disabling Java VM on Startup", "Increasing System Swap Space", "Using the 3GB Switch on Windows Systems", "Freeing Up System Resources on Windows Systems".

Try to reduce the memory needs of your programs.

• Use smaller integer types for index vectors.
• Store numerical values in SINGLE precision, if this is accurate enough.
• Pre-allocate ever. Never let an array grow.
• Pre-allocate absolutely really ever carefully.
• Reduce the number of open figures.
• Install as much RAM as possible.

Thank you for your answer. :-)

I will try it.
