Curve Fitting by Optimization

---

Here you can fit a polynomial a₀+a₁x+a₂x²+.... to a set of

data points ((x_i,y_i), 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.

Enter the degree of polynomial 'n'

Enter number of data points 'np'

Least Squares Value

Co-efficients of the Polynomial
