mxGetM (Fortran)

Number of rows in mxArray

Fortran Syntax

#include "fintrf.h"
mwPointer mxGetM(pm)
mwPointer pm

Description

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.

Input Arguments

expand all

Pointer to an mxArray array, specified as mwPointer.
