Hi there!
I'm a chemist and for the first time I need to use a polynomial fitting of the 4th grade to approximate some experimental datas. I made this afternoon a program that worked from top to bottom then I made some mistakes during the saving I think, and my program is no more able to run...here to you a printscreen.
I'm a new utent of those softwares and I'm not a matematician so, can someone tell me what happened?
