That is true!

I have no skills at the time to contribute then. :-(

Lack of JIT compiling. All of the Matlab files are tick-tocking loops,
sometimes nested loops. Also, unnecessary loops. This is poorly
vectorised code. The more nesting, the worse the difference becomes.

Implement JIT compiling or vectorise this code.
