2. Variational method (15 pts each, 30 points total) Fitting of a collection of the data points to a given functional form can be done using variational method. Say, the measured data points are given in the table: 1 0 1 Assuming the fitting function is f(x; α, β, ), where α, β, are the variation parameters, the fitting error functional can be formulated as: F[f-E:(f(xi; α., )-%)2. This function is a mere function of the variational parameters, so the...

Curve Fitting It is desired to fit a polynomial curve through evenly spaced (x-direction) points. The general form of a polynomial is: f(x) = 4x + 4-1x* +ajx + ao If one wishes to fit a curve through, say 4 points, one would need a 3rd degree polynomial (n = 3) such that 4 unknown constants could be evaluated. In the absence...
