Description
Interface Summary | |
---|---|
ParametricRealFunction | An interface representing a real function that depends on one independent variable plus some extra parameters. |
Class Summary | |
---|---|
CurveFitter | Fitter for parametric univariate real functions y = f(x). |
HarmonicCoefficientsGuesser | This class guesses harmonic coefficients from a sample. |
HarmonicFitter | This class implements a curve fitting specialized for sinusoids. |
HarmonicFunction | Harmonic function of the form f (t) = a cos (ω t + φ) . |
PolynomialFitter | This class implements a curve fitting specialized for polynomials. |
WeightedObservedPoint | This class is a simple container for weighted observed point in
curve fitting . |
This package provides classes to perform curve fitting.
Curve fitting is a special case of a least squares problem
were the parameters are the coefficients of a function f
whose graph 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
(xi, yi).
