Number of rows in mxArray
#include "fintrf.h" mwPointer mxGetM(pm) mwPointer pm
mxGetM returns the number of rows in the specified array. The
term rows always means the first dimension of the array, no matter
how many dimensions the array has. For example, if pm points to a
four-dimensional array having dimensions
8-by-9-by-5-by-3,
then mxGetM returns 8.
Note
Fortran does not have an equivalent of size_t. mwPointer is a preprocessor macro
that provides the appropriate Fortran type. The value returned by
this function, however, is not a pointer.
