Determine whether mxArray represents data as double-precision, floating-point numbers
#include "fintrf.h" integer*4 mxIsDouble(pm) mwPointer pm
mxIsDouble returns 1 if the
mxArray stores its real and imaginary data as double-precision,
floating-point numbers. Otherwise, it returns 0.
Older versions of MATLAB® store all mxArray data as double-precision,
floating-point numbers. However, starting with MATLAB Version 5 software, MATLAB can store real and imaginary data in other numerical formats.
In Fortran, calling mxIsDouble is equivalent to calling:
mxGetClassName(pm) .eq. 'double'
