mxCreateLogicalScalar (External Interfaces Reference)

Create scalar, logical mxArray initialized to false

C Syntax

#include "matrix.h"
mxArray *mxCreateLogicalScalar(mxLogical value);

Arguments

value
The desired logical value, logical 1 (true) or logical 0 (false), to which you want to initialize the array.

Returns

A pointer to the created mxArray, if successful. mxCreateLogicalScalar is unsuccessful if there is not enough free heap space to create the mxArray. If mxCreateLogicalScalar is unsuccessful in a MEX-file, the MEX-file prints an "Out of Memory" message, terminates, and control returns to the MATLAB prompt. If mxCreateLogicalScalar is unsuccessful in a stand-alone (nonMEX-file) application, the function returns NULL.

Description

Call mxCreateLogicalScalar to create a scalar logical mxArray. mxCreateLogicalScalar is a convenience function that can be used in place of the following code:

pa = mxCreateLogicalMatrix(1, 1);
*mxGetLogicals(pa) = value;

When you finish using the mxArray, call mxDestroyArray to destroy it.
