matGetNextVariable

Read next mxArray from MAT-file

Fortran Syntax

Arguments

mfp
   Pointer to MAT-file information.

name
   Address of the variable to contain the mxArray name.

Description

matGetNextVariable allows you to step sequentially through a MAT-file and read all the mxArrays in a single pass. The function reads the next mxArray from the MAT-file pointed to by mfp and returns a pointer to a newly allocated mxArray structure. MATLAB returns the name of the mxArray in name.

Use matGetNextVariable immediately after opening the MAT-file with matOpen and not in conjunction with other MAT-file routines. Otherwise, the concept of the next mxArray is undefined.

matGetNextVariable returns 0 when the end-of-file is reached or if there is an error condition.

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