Hello professor Rodrigo:
I followed your suggestion that the -cxx flag was removed from the Makefile
in $MyIpoptDir/build/Ipopt/contrib/Matlabinterface/src. After that, the
MatlabInterface is installed successfully in my Laptop. It works very well.

You did a very great job. Thank you very much !
Best regards
