MATLAB: Increase Memory in Matlab

out of memory

Hello,
I get some out of memory error when I am loading Matfiles (~20,000) from a folder to Matlab.
The error is:
Exception in thread "Thread-31" java.lang.OutOfMemoryError: GC overhead limit exceeded at java.lang.String.substring(Unknown Source)
———————————————————————-
When I run the command, memory:
Maximum possible array: 39487 MB (4.140e+010 bytes) *
Memory available for all arrays: 39487 MB (4.140e+010 bytes) *
Memory used by MATLAB: 667 MB (6.992e+008 bytes)
Physical Memory (RAM): 24574 MB (2.577e+010 bytes)
Limited by System Memory (physical + swap file) available.
—————————————————————————
I would like to know if I increase the memory available to Matlab, would this fix the problem? Is it recommendable ? If yes, how?
I am running a Windows 7 64 bit.
Thanks a lot in advance.
Cheers,

The problem appears to be in the memory allocated for java, rather than for MATLAB itself. There have been a few questions about how to increase the java memory, but I do not recall the exact solution at the moment; I think it involved the java.opts file.
