mxIsLogical (C and Fortran) - Determine whether mxArray is of type mxLogical
C Syntax
#include "matrix.h"
bool mxIsLogical(const mxArray *pm);
Fortran Syntax
integer*4 mxIsLogical(pm)
mwPointer pm
Arguments
- pm
Pointer to an mxArray
Returns
Logical 1 (true) if pm points
to a logical mxArray, and logical 0 (false)
otherwise.
Description
Use mxIsLogical to determine whether MATLAB software
treats the data in the mxArray as Boolean (logical).
If an mxArray is logical, MATLAB treats all
zeros as meaning false and all nonzero values as
meaning true. For additional information on the
use of logical variables in MATLAB software, type help
logical at the MATLAB prompt.
