You may be confused.
MathWorks is not here as a service company, where they will write software to your specs to accomplish your thesis. (I can't imagine any companies that would offer such a service for free anyway.)
That is also not true of Answers. We will offer help if you have a problem, if you don't understand something in MATLAB, we can help you to fix a problem. If you do have a question, be as clear as possible. It often helps if you give a small example problem, where you know what you want as an answer, but don't know how to get there. If you have data, then provide it, since we can then show how to solve the problem on your data. If you get into trouble, don't show a picture of your code, but paste in code as readable text. That makes it easy for someone to help you. If you get an error message that you do not understand, then show the complete text of that error message, everything in red. That helps someone to quickly know what is the problem.
But we also will not write code to your specifications to perform the computations on your thesis. That is something you would in theory need to pay a consultant to do, not that it would be remotely appropriate for a thesis, since that should be your work, not the work of someone else.
At the same time, MATLAB is a wonderful tool, one that I truly wish I was using when I was in grad school to do the computational work I needed. So MATLAB can and will do great things to support your research. You just need to write the code for that yourself. But doing so using MATLAB can be far more efficient than using some other choices of computing environments. (Of course, there are other computing environments that would also be of great help too. I don't wish to claim that MATLAB is the greatest for all people and all problems. For me, it is the best choice and my preferred choice.)
