mxCreateLogicalMatrix (C) - Create 2-D, logical mxArray initialized to false

C Syntax

#include "matrix.h"
mxArray *mxCreateLogicalMatrix(mwSize m, mwSize n);

Arguments

m

The desired number of rows

n

The desired number of columns

Returns

A pointer to the created mxArray, if successful. If unsuccessful in a stand alone (non-MEX-file) application, mxCreateLogicalMatrix returns NULL. If unsuccessful in a MEX-file, the MEX-file terminates and control returns to the MATLAB prompt. mxCreateLogicalMatrix is unsuccessful when there is not enough free heap space to create the mxArray.

Description

Use mxCreateLogicalMatrix to create an m-by-n mxArray of mxLogical elements. mxCreateLogicalMatrix initializes each element in the array to logical 0.

Call mxDestroyArray when you finish using the mxArray. mxDestroyArray deallocates the mxArray.
