Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which focuses more on questions of statistical inference such as how much uncertainty is present in a curve tha… WebMay 8, 2024 · Learn more about fit, curve fitting, plot, rsquared MATLAB Hi, I am trying to use fitlm and rsquared ordinary functions and I can't figure out where the errors comes from.
