Nettet• expfit(vx, vy, [vg])—Returns a vector containing three coefficients for an exponential curve of the form A · exp(b·x) + Cthat best approximates the data in vxand vy. The expfitfunction employs the Levenberg-Marquardt method for minimization. For an exponential fit that differs from the form above, use genfit. Arguments Nettetmodel the data. We will use the Mathcad built-in functions "intercept" and "slope". b intercept(x,V) b = 7.139.10 2 m slope(x,V) m = 2.622.10 2 fit(x) b m.x This is our linear … patsy restaurant west orange nj
