Class NevilleInterpolator
java.lang.Object
org.apache.commons.math.analysis.interpolation.NevilleInterpolator
- All Implemented Interfaces:
- java.io.Serializable, UnivariateRealInterpolator
public class NevilleInterpolator
- extends java.lang.Object
- implements UnivariateRealInterpolator, java.io.Serializable
Implements the
Neville's Algorithm for interpolation of real univariate functions. For
reference, see Introduction to Numerical Analysis, ISBN 038795452X,
chapter 2.
The actual code of Neville's evalution is in PolynomialFunctionLagrangeForm,
this class provides an easy-to-use interface to it.
