array size limit issues

Hello, I'm trying to run a code which basically calculates the radial intensity profile of a disk at every stack and then plots it over time. The videos I analyze however are quite long (200 to 900 stacks--> 1-4Gb) and heavy.

While running the code, in one of the final steps I have the following error:

"Requested 341x3104952 (7.9GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause MATLAB to become unresponsive. See array size limit or preference panel for more information".

Do you know how can I increase the array size limit?

Thank you in advance for your help!

In addition to the preferences to which Walter directed you, if you're working with big data the tools in MATLAB designed to operate on big data may be of use to you.
