Memory usage by Matlab

Does increasing my computer's RAM allow Matlab to store and process variables of increased size?

Thank you

Yes.

Answer 2

If you are using 32 bit MATLAB, then increasing memory will not allow you to go larger than 3 Gb including MATLAB and all relevant libraries (and you would have to use a special boot-time flag to get 3 Gb.)

If you are using 64 bit MATLAB, then increasing memory does allow you to process larger arrays. You could also increase swap space instead of adding RAM, but swap space can be very very slow.

I am using the 64 bit MATLAB. Thank you

Then Yes.

The limit with current 64 bit x64 processors is 256 Terabytes per node. Your computer probably doesn't have enough memory slots for that, though!
