Fourier Series Fitting using Fit function - MATLAB Answers

WebI have arrays of x and y data points (around 50 points in each set) to which I want to find the best fit (defined as minimizing least squares) using any alpha, beta and gamma. The solutions online recommend the curve fitting toolbox, which I do not have on my machine and am unable to install. I only have the barebones MATLAB 2015b version. WebThis is especially true if the coefficients are not constrained: with the forms of the two terms being the same, exchanging the three model parameters between the two terms gives you the same function value, so the fitting cannot possibly decide whether (for example) it is the first term or the second term that should be multiplied by 0.83.
