First, I had to modify the source code to get it compiled under R2017b
API. One should test "#if MX_HAS_INTERLEAVED_COMPLEX" instead of "#if
defined(MX_HAS_INTERLEAVED_COMPLEX)", since the macro is defined in
both APIs. See the fixed source code attached.

I also attach the output of nm for both APIs (generated using MATLAB
R2019b, under Debian "Buster" 10 amd64).
