, and logical 0

Use mxIsLogical
to determine whether MATLAB treats the data in the mxArray
as Boolean (logical). If an mxArray
is logical, then 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, type help logical
at the MATLAB prompt.
