matGetVariable (C and Fortran)

Array from MAT-file

C Syntax

#include "mat.h"
mxArray *matGetVariable(MATFile *mfp, const char *name);

Fortran Syntax

#include "mat.h"
mwPointer matGetVariable(mfp, name)
mwPointer mfp
character*(*) name



Pointer to MAT-file information


Name of mxArray to get from MAT-file


Pointer to a newly allocated mxArray structure representing the mxArray named by name from the MAT-file pointed to by mfp.

matGetVariable returns NULL in C (0 in Fortran) if the attempt to return the mxArray named by name fails.


This routine allows you to copy an mxArray out of a MAT-file.

Use mxDestroyArray to destroy the mxArray created by this routine when you are finished with it.


See the following examples in matlabroot/extern/examples/eng_mat.
