mxCreateLogicalMatrix (External Interfaces/API Reference)

Create two-dimensional, logical mxArray initialized to false

C Syntax

#include "matrix.h"
mxArray *mxCreateLogicalMatrix(int m, int 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 (nonMEX-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 logical (true and false) elements. mxCreateLogicalMatrix initializes each element in the array to false.

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