| mxCalloc (C and Fortran) | ||||||||
| The memory manager maintains a list of all memory allocated by mxCalloc. The memory manager automatically frees (deallocates) all MEX-file parcels when control returns to the MATLAB prompt. InstandaloneMATLABCapplications,mxCalloc calls the ANSI® C calloc function. By default, in a MEX-file, mxCalloc generates nonpersistent mxCalloc data. In other words, the memory manager automatically deallocates the memory as soon as the MEX-file ends. If you want the memory to persist after the MEX-file completes, call mexMakeMemoryPersistent after calling mxCalloc. If you write a MEX-file with persistent memory, be sure to register a mexAtExit function to free allocated memory in the event your MEX-file is cleared. When you finish using the memory allocated by mxCalloc,callmxFree to deallocate the memory. C See Examples • explore, c in the mex subdirectory of the examples directory • phonebook.c and revord.c in the refbook subdirectory of the examples directory For additional examples, see mxcalcsinglesubscript.c and mxsetdimensions.c in the mx subdirectory of the examples directory.
