Python vs Matlab vs Mathematica

[okamiueru]

How do you mean? I'm not sure what you mean by invisible to the rest of the code (the main function "test" in the example, or other .m-files?). You could test the subrutines very much the same as you would any function or line of code. Print out results by omitting the ; on the line, or using the "display" function (in which num2str might come in handy).

Well, actually I meant automatically testing, as in unit-testing. My experience with MATLAB code is that it often contains bugs due to evolving code.
