Editor's Note: This file was selected as MATLAB Central Pick of the Week

This utility measures the size of the largest contiguous block of virtual memory available to MATLAB® (after startup), then recommends solutions to increase its size should it be smaller than typical. The recommended solutions can help to reduce the occurrence of 'Out of Memory' errors. If results do not make sense, please email the author of this submission, sending output of command 'feature dumpmem' after startup.
