Why are the built-in functions in Matlab so much faster then the ones that you write yourself?
yes,
matlabalikes usually use wrapper functions for linear algebra library routines written in a low level language (usuallyFortran) such asBLAS,ATLASorLAPACK.you can read more about this in here
also see this question if you’re curious how much overhead does function wrapping costs (basically none). results are for
C++,pythonandnumpybut I believe they are applied to matlab as well.
