Memory Management

MATLAB now implicitly destroys (by calling mxDestroyArray) any arrays created by a MEX-file that are not returned in the left-hand side list (plhs()). Consequently, any misconstructed arrays left over at the end of a MEX-file's execution have the potential to cause memory errors.

In general, we recommend that MEX-files destroy their own temporary arrays and clean up their own temporary memory. For additional information on memory management techniques, see the sections Memory Management and Memory Management Compatibility Issues.
