WebJan 8, 2010 · A more general solution might be to use polyfit. You need to use polyfit to fit a line to your data. Suppose you have some data in y and you have corresponding domain values in x, (ie you have data approximating y = f (x) for arbitrary f) then you can fit a linear curve as follows: p = polyfit (x,y,1); % p returns 2 coefficients fitting r = a_1 ...
