mxCreateLogicalMatrix (C)

2-D logical array

C Syntax

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

Arguments

m

Number of rows

n

Number of columns

Returns

Pointer to the created mxArray, if successful. If unsuccessful in a standalone (non-MEX file) application, returns NULL in C (0 in Fortran). If unsuccessful in a MEX file, the MEX file terminates and returns control to the MATLAB® prompt. The function 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.

Examples

See the following examples in matlabroot/extern/examples/mx.

Introduced before R2006a
