Returns
true if array_ptr is a numeric array containing complex data, and false otherwise. If array_ptr points to a cell array or a structure array, then mxIsComplex returns false.
Description
Use mxIsComplex to determine whether or not an imaginary part is allocated for an mxArray. The imaginary pointer pi is NULL if an mxArray is purely real and does not have any imaginary data. If an mxArray is complex, pi points to an array of numbers.
