Was MATLAB ever the fastest kid?

What's outlined in the article has, from my PoV at least, been true since 1980 at least (and older coders will likely in with earlier tales): handy implementation and simulation libraries generally work and provide good reference results to check against but almost always you can get a magnitude order faster if you can put the time in.

I put the earlier pre-2008 epoch models for earths gravity and magnetics through a similar workout sometime ago, for our use case we spent some time and money to make a custom TI DSP chip pipeline to get the turn around that made data exploration playful rather than an overnight grind.
