mwSize (C and Fortran)

Type for size values

Description

mwSize is a type that represents size values, such as array dimensions. Use this function for cross-platform flexibility. By default, mwSize is equivalent to int in C. mwSize is an unsigned type, meaning a nonnegative integer.

When using the mex -largeArrayDims switch, mwSize is equivalent to size_t in C. In Fortran, mwSize is similarly equivalent to INTEGER*4 or INTEGER*8, based on platform and compilation flags.

The C header file containing this type is:

#include "matrix.h"

In Fortran, mwSize is a preprocessor macro. The Fortran header file containing this type is:

#include "fintrf.h"

Introduced before R2006a
