We have tried to make it straightforward to use even if one is not too familiar with C++. We encourage users to experiment with translating their MatLAB components to C++ if they are interested in the performance boost.
One of the main challenges of translating scientific code from MatLAB to C++ is finding equivalent numerical procedures to those supplied by MatLAB. We have supplied some functions in the project and we are very open to adding any mathematical functionality desired by the user. We may even have those desired procedures already embedded in OptiSystem itself, which we could extract.
