<p>Do you know some articles that explains in a better fashion what is needed, namely the mathematical process behind the results shown in the article? Code examples in other languages welcome.

You might want to be more specific here. What part are you struggling with in that paper?  At a glance it appears well explained —no mathemagic. Or is converting summations &co. to quick vector calculus Matlab without for-loops or converting a string (cell of characters) to a vector, which in Matlab is annoying?

It is not a problem about the code. It is a problem about the various passages that I should follow. Basically, reading the article, it is not very clear about what kind of statistics I should follow to compute the complexity state and the repetition vector and what kind of procedure I have to do to calculate these statistics over the amino acid sequence. The article is not very clear and I was searching for some more detailed threads to follow in order to understand what I have to do in whatever programming language.

I want to implement SEG in my MATLAB environment and I'm relying on Wootton and Federhen ([1993](https://www.sciencedirect.com/science/article/abs/pii/009784859385006X))
