mxCreateLogicalMatrix (C)

2-D logical array

C Syntax

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



Number of rows


Number of columns


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.


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.

Introduced before R2006a
