mxSetData (Fortran) - Set pointer to data elements in nonnumeric

        mxArray - MATLAB ([original](https://www.mathworks.com/help/matlab/apiref/mxsetdata%5Ffortran.html)) ([raw](?raw))

For a complex numeric mxArray, themxSetData function sets different values based on themex build option.

If you build the MEX file with the default release-specific option (-R2017b), then the function sets the elements of the array to the real-only values.

If you build the MEX file with the -R2018a option, then:

• When pm is a real array, pa becomes the real component of pm.
• When pm is complex array, pa also must be complex. Otherwise, the elements of pa become interleaved real and imaginary values, not real-only values.
