mxIsLogical
True ifmxArray
is Boolean
#include "matrix.h" bool mxIsLogical(const mxArray *array_ptr);array_ptr
true
if the mxArray's
logical flag is on; otherwise, returns false
. If an mxArray
does not hold numerical data (for instance, if array_ptr
points to a structure mxArray
or a cell mxArray
), then mxIsLogical
automatically returns False
.
Use mxIsLogical
to determine whether MATLAB treats the data in the mxArray
as Boolean (logical) or numerical (not logical).
If an mxArray
is logical, then MATLAB treats all zeros as meaning false
and all nonzero values as meaning true
.
