Basically, I have a symsum which I intend on feeding into a fittype() function.
The fittype is of the form (V0/2) + (V1/2)*cos(1*x) + (V2/2)*cos(2*x) +... (Vn/2)*cos(n*x) where each Vn is an independent variable in a non-linear least squares.
Those Vn variables are going into a matrix so the values need to be extractable, right now I'm using coeffvalues(fitresult) or manually getting them out with fitresult.V0, V1 etc (that could be a question on its own).
I have the sum of cos funcs
syms x n
Func = symsum((1/2)*cos(n*x),n,[1 5])
but I can't figure out how to (1) create an array of variables V0:Vn and outputting them as variables and (2) how to combine those with a symsum output into the fittype given above.
