mxSetLogical (Obsolete)

Convert an mxArray to logical type

Note    As of MATLAB version 6.5, mxSetLogical is obsolete. Support for mxSetLogical may be removed in a future version.

C Syntax

• #include "matrix.h"
  void mxSetLogical(mxArray *array_ptr);
  

Arguments

array_ptr
   Pointer to an mxArray having a numeric class.

Description

Use mxSetLogical to turn on an mxArray's logical flag. This flag tells MATLAB that the array's data is to be treated as Boolean. If the logical flag is on, then MATLAB treats a 0 value as meaning false and a nonzero value as meaning true. For additional information on the use of logical variables in MATLAB, type help logical at the MATLAB prompt.

Examples

See mxislogical.c in the mx subdirectory of the examples directory.
