I'm J1 visiting scholar from China to the US. my adviser is nice before and taught me code line by line. I also studied very hard to modify this code to run the new application. But these 4-5 months, he got mad at me because I haven't got a good result. I even cannot discuss with him, every time I ask him a question he will get mad easily even I told him I used MATLAB to help me. He will sneer me "you can only use MATLAB". I don't understand why he did this to me?

then finally I found what he suggested me is not right, that's why I struggled. today I discuss with him about the U which he said this method is wrong. I spent few months to deal with this problem and finally, i found it's right, so no need to correct this part actually. however, he still gets mad and unsatisfied that I told him his suggestion has some problem.

Ok, there are so many occasions that I accept his suggestions to edit the code but code even cannot run. finally, I edit the code in my idea and fix the code which approves I'm right he is wrong. there are so many situations that he makes my research harder. before he really taught me how to write code but now he's unsatisfied about me every time.

what should I do?
1, listen to him to write wrong code to get the wrong result?
2, do it by myself to write correct code get right result but he doesn't buy it?

Sounds like the supervisor has a big ego and doesn't like you telling him he's wrong. Maybe it's the way you're saying it? Some people take offence at the smallest things.

If it was me, I would quietly find someone else to check what I was doing, and if I was still right, then just carry on with it and not keep highlighting to the supervisor that I was right.

I would be careful with this supervisor. He doesn't sound very professional. Best to keep your head down and do what Tree of Life suggests. Hopefully he will start acting nice again once it has blown over (and you'll be prepared for him the possibility of him behaving like this again in the future).
