matGetVariable

Read mxArrays from MAT-files

C Syntax

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

Arguments

mfp
   Pointer to MAT-file information.

name
   Name of mxArray to get from MAT-file.

Description

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

matGetVariable reads the named mxArray from the MAT-file pointed to by mfp and returns a pointer to a newly allocated mxArray structure, or NULL if the attempt fails.

Be careful in your code to free the mxArray created by this routine when you are finished with it.

Examples

See matcreat.c and matdgns.c in the eng_mat subdirectory of the examples directory for sample programs that illustrate how to use the MATLAB MAT-file routines in a C program.
