MEM displays memory usage to the command window.

MEM displays memory usage to the command window.

As many programmers have experienced, Matlab grinds to a near standstill when large amounts of memory are used in the workspace. MEM gives a succinct report of the memory used, so the programmer can see which variables are using the most memory (and thus causing the slow-down).

This function is only useful for programmers who develop codes containing hundreds of variables, in which case they might not remember the size of each variable off the top of their head. MEM helps the programmer determine how best to streamline the memory usage and improve the speed of his or her code.
