MATLAB: How to solve that out of memory

out of memory

Hi,
this is my code,

but I run it, matlab show this message
??? Not enough memory available for 537 frames.
Error in ==> mmreader.read at 67
        videoFrames = read(getImpl(obj));
Error in ==> GUIf1 at 11
vid3 = read(obj3);
I don't know that I should how to do.
My computer is 32 bits and RAM is 4.0G.
Pleas give me some advice. Thank you.

If you use a 64 bit system and Matlab version, you can use more than the 3GB RAM, which are available under Matlab/32 only.
