Appreciate the comment actually! It's good feedback -- we weren't sure if it's mixing work/memes too much, and keeping our materials clean like engineering docs are probably a good way to go. We may edit it out of the post.

Cheers for the comment!

It's open source / free. But yes, of course we want people to try it and get value from it.

Seeing in MATLAB code how ode45 is implemented != how the thing is running on the machine. That's a very small top slice.

But okay -- as I mentioned, you're entitled to your views!

Shameless plug for RunMat (we wrote this blog article, also an open source alternative for MATLAB):

Yep -- Octave was very helpful for me in school.

Octave is not particularly fast.

RunMat is very fast (orders of magnitude -- see benchmarks).
