Hi,
I am trying to do a best fit where the fitting parameters are A, B, and C.
I have my experimental data: col(A) (x-axis) versus col(Exp) (y-axis). I have 3 more columns (col(G), col(H) and col(I)) that I have to combine to fit to the experimental data. Basically, I have to find the fitting parameters: G1, H1 and I1 that will enable me to fit:
col(Exp)= G1 * col(G) + H1 * col(H) + I1 * col(I)
I have not found the command that will allow me to put columns into the fitting tool rather than a function of x.
