If you go deep enough, sometimes you can find the models on one author&#x27;s university website.  Then you&#x27;ll scream.<p>Often you&#x27;ll find the source program, but then discover it&#x27;s a 12,000 line matlab file with no comments, no spaces between lines, and lots of copy&#x2F;paste.<p>Step one of reproducible results: stop using matlab.
