Hi, need some help to set up Mathematica NB to generate polynomial equations for surface fits for some data sets. Basically I need equations for Core loss (P) in terms of two variables, B and f.
Attached is a spreadsheet with the data. The data is for specific core loss (Pc) in terms of two variables - f (Frequency) and B (flux density).
There are 14 small material tables highlighted in yellow. I would like a polynomial equation for Core Loss in terms of f and B for each. Probably second order equations are fine. Also would like the NB copy so I can make changes in the future.
Regards, Chris
