mxCreateLogicalArray (C) - Create N-D logical mxArray initialized to false

C Syntax

#include "matrix.h"
mxArray *mxCreateLogicalArray(mwSize ndim, const mwSize *dims);

Arguments

ndim

Number of dimensions. If you specify a value for ndim that is less than 2, mxCreateLogicalArray automatically sets the number of dimensions to 2.

dims

The dimensions array. Each element in the dimensions array contains the size of the array in that dimension. For example, setting dims[0] to 5 and dims[1] to 7 establishes a 5-by-7 mxArray. There should be ndim elements in the dims array.

Returns

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

Description

Call mxCreateLogicalArray to create an N-dimensional mxArray of mxLogical elements. After creating the mxArray, mxCreateLogicalArray initializes all its elements to logical 0. mxCreateLogicalArray differs from mxCreateLogicalMatrix in that the latter can create two-dimensional arrays only.

mxCreateLogicalArray allocates dynamic memory to store the created mxArray. When you finish with the created mxArray, call mxDestroyArray to deallocate its memory.

Any trailing singleton dimensions specified in the dims argument are automatically removed from the resulting array. For example, if ndim equals 5 and dims equals [4 1 7 1 1], the resulting array is given the dimensions 4-by-1-by-7.
