The fastest OpenViBE behaviour: using C++ or Matlab engine

Post by gibfen »

Hi everyone!

It is just a simple question. I was wondering if using C++ code instead of Matlab's engine (with a Matlab script) is faster or not necessarily. ¿?

I think that Matlab algorithms are quite good and quite fast, but maybe the open libraries for signal processing with C++ aren't as good as Matlab's ones. So C++ could be faster, but, maybe with non-free libraries. ¿?

Considering that the time OpenViBE needs in order to establish a connexion with Matlab's engine is beside the point, I also would like to know (if somebody knows/tested), if the fact of continuously accessing to Matlab's engine (because we are using Matlab scripting with OpenViBE) makes the "process" slower than using directly C++ code (supposing that this C++ code would be exactly the equivalent to Matlab's one). ¿?

Best!
