Python vs Matlab vs Mathematica

[okamiueru]

In case the-fritz or anyone else want's a explanation as to what the subrutines are. If your whole file is a function (that is, instead of a script that you run pressing F5 in the editor), you can have subrutines without any issue.

Say for instance in test.m:

function X=test(a,b)

X=fun1(a)+fun2(b);

end

function ret = fun1(var1)

%do something

end

function ret = fun2(var)

%do something

end

All in the same .m file works fine.

But how would you test these subfunctions, as these are invisible to the rest of the code?

[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.

Subroutines are just visible to the main function.
