款好用且免费的曲线拟合工具CurveFitter

Curve fitting class based on the Simplex method described in the article "Fitting Curves to Data" in the May 1984 issue of Byte magazine, pages 340-362. 2001/02/14: Modified to handle a gamma variate curve. Uses altered Simplex method based on method in "Numerical Recipes in C". This method 款好用且免费的曲线拟合工具CurveFitter tends to converge closer in less iterations. Has the 款好用且免费的曲线拟合工具CurveFitter option to restart the simplex at the initial best solution in case it is "stuck" in a local minimum (by default, restarted twice). Also includes settings dialog option for user control over simplex parameters and functions to evaluate the goodness-of-fit. The results can be easily reported with the getResultString() method.

Apache Commons CurveFitter CurveFitter(final MultivariateVectorOptimizer optimizer) Simple constructor.

Apache Commons CurveFitter CurveFitter(final 款好用且免费的曲线拟合工具CurveFitter MultivariateVectorOptimizer optimizer) Simple constructor.

Introduction

The method CurveFitter() is a constructor.

Syntax

The method CurveFitter() 款好用且免费的曲线拟合工具CurveFitter from CurveFitter is declared as:

The method CurveFitter() has the following parameter:

  • MultivariateVectorOptimizeroptimizer - Optimizer to use for the fitting.

Example

The following code shows how to use CurveFitter from org.apache.commons.math3.fitting.

Specifically, the code shows you how to use Apache Commons CurveFitter CurveFitter(final MultivariateVectorOptimizer optimizer)

Make "CurveFitter" a generic class

In order to enhance compile-time robustness, it is proposed to parameterize the "CurveFitter" class with the type of the function to be used for the fit, i.e.:

Thus 款好用且免费的曲线拟合工具CurveFitter enforcing that instances of subclasses like "PolynomialFitter" defined as
