Pointer to MAT-file information
Pointer to the variable containing the

error condition. In C, use
the Standard C Library to determine status.
matGetNextVariableInfo loads only the array header information,
including everything except
jc, from the current file
jc are nonzero values when loaded with
sets them to

this data back to the MATLAB® workspace or save it to MAT-files.

The order of variables returned from successive calls to
matGetNextVariableInfo is not guaranteed to be the same order
in which the variables were written.
