matGetDir

Get directory of mxArrays from MAT-file

Fortran Syntax

• integer*4 function matGetDir(mfp, num)
  integer*4 mfp, num
  

Arguments

mfp
   Pointer to MAT-file information.

num
   Address of the variable to contain the number of mxArrays in the MAT-file.

Description

This routine enables you to get a list of the names of the mxArrays contained within a MAT-file.

matGetDir returns a pointer to an internal array containing pointers to the names of the mxArrays in the MAT-file pointed to by mfp. The length of the internal array (number of mxArrays in the MAT-file) is placed into num. The internal array is allocated using a single mxCalloc. Use mxFree to free the array when you are finished with it.

matGetDir returns 0 and sets num to a negative number if it fails. If num is zero, mfp contains no mxArrays.

MATLAB variable names can be up to length 32.
