How can I get a matlab code of articles?

on projected gradient method

[Dyuman Joshi]

Your question is unclear.

Do you want full code from a research article? Then ask the authors.

[John D'Errico]

@biratu lemessa - As has been said, if you need code from some specific paper, then you might try contacting the appropriate individuals, or you need to write the code. We do not write code on demand here. That is not the purpose of Answers. You might also try a Google search, or you might do a search on the File Exchange. You might get lucky and find someone has posted code to solve your problem. But you can do a search as easily as can anyone else. And only you know exactly what you are looking to find.

So either start searching, or start writing. If you actually have a question about MATLAB at some point, then ask it here.
