Curve Fitting by Optimization
Here you can fit a polynomial a0+a1x+a2x2+.... to a set of
data points ((xi,yi), i=1..np) using optimization. Monitor the least squares value to choose the optimal degree of the polynomial. You can enter the degree of the polynomial and the number of data points in the form below and click on 'Fit Curve' to submit the form. Then you will be asked to enter the data points interactively.
