mxClearLogical (Obsolete)

Clear the logical flag

Note    As of MATLAB version 6.5, mxClearLogical is obsolete.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

C Syntax

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

Arguments

array_ptr
   Pointer to an mxArray having a numeric class.

Description

Use mxClearLogical to turn off the mxArray's logical flag. This flag, when cleared, tells MATLAB to treat the mxArray's data as numeric data rather than as Boolean data. If the logical flag is on, then MATLAB treats a 0 value as meaning false and a nonzero value as meaning true.

Call mxCreateLogicalScalar, mxCreateLogicalMatrix, mxCreateNumericArray, or mxCreateSparseLogicalMatrix to turn on the mxArray's logical flag. For additional information on the use of logical variables in MATLAB, type help logical at the MATLAB prompt.

Examples
