WebSep 25, 2024 · How can I fit a curve to the red data points in MATLAB?-----I have tried using polyfit, smoothingspline, pchip and other curve-fitting tools, but all of them connect the wrong data points together, since this graph is actually x = f(y). In MS Excel, if I switch the axes so the curve becomes a one-to-one function where y = f(x), I can easily fit ... WebTo fit a polynomial model to the data, specify the fitType input argument as "poly#" where # is an integer from one to nine. You can fit models of up to nine degrees.
