WebMar 31, 2024 · $\begingroup$ @rhermans in abstract terms I would argue that polynomial fits are a bad idea because it is very tricky to get the polynomial order right: too low, you get a bad fit; too high, you get oscillations. In general, there is no good answer here and everything depends on the concrete situation. Fitting is much more than plugging in … WebSep 30, 2016 · The poly function takes arguments as roots of a polynomial. Like if x-2=0 is the equation, poly(2) is enough to find the polynomial matrix. So, we dont need to put extra 'x' in poly.
