Fitter for parametric univariate real functions y = f(x).
Fits points to a
Guesses the parameters
Class that implements a curve fitting specialized for sinusoids.
This class guesses harmonic coefficients from a sample.
This class implements a curve fitting specialized for polynomials.
This class is a simple container for weighted observed point in
Curve fitting is a special case of a least squares problem
were the parameters are the coefficients of a function
y=f(x) should pass through sample points, and
were the objective function is the squared sum of residuals
f(xi)-yi for observed points
