WebFit Polynomial to Trigonometric Function. Generate 10 points equally spaced along a sine curve in the interval [0,4*pi]. x = linspace (0,4*pi,10); y = sin (x); Use polyfit to fit a 7th-degree polynomial to the points. p = polyfit (x,y,7); Evaluate the polynomial on … 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 …
