well, I'm an engineering student , I've taken three classes that involve mathlab. one of them is like the introduction and the basics , the second is automatic control ( I'm really struggling with the translation here since we studied them in french . the french name of this class is " automatique lineaire" ) it involves studying the stability of first order and 2nd order systems , anyway.. and last, there's a class where we applied boundary elemnt methods and diferential equations solving on mathlab.
honestly , I don't understand how these people claim to be able to do the work in one day ( I've done a lot of projects and problems on mathlab , and I know it can be extremely difficult) so unless they're really experts or professors or professional engineers , I don't think they really understand what they're dealing with.
If you decide to hire me , you should first send me the documents so I can honestly tell you if I'm capable of solving them or not.
