mexMakeArrayPersistent

Make an mxArray persist after the MEX-file completes

C Syntax

Arguments

array_ptr
   Pointer to an mxArray created by an mxCreate* routine.

Description

By default, mxArrays allocated by mxCreate* routines are not persistent. The MATLAB memory management facility automatically frees nonpersistent mxArrays when the MEX-function finishes. If you want the mxArray to persist through multiple invocations of the MEX-function, you must call mexMakeArrayPersistent.
