Class EnhancedSimpsonIntegratorSampler

java.lang.Object
  org.jscience.mathematics.analysis.quadrature.EnhancedSimpsonIntegratorSampler

All Implemented Interfaces:

SampledMappingIterator

public class EnhancedSimpsonIntegratorSampler
extends java.lang.Object
implements SampledMappingIterator

This class implements an enhanced Simpson integrator as a sample.

A traditional Simpson integrator is based on a quadratic approximation of the function on three equally spaced points. This integrator does the same thing but can handle non-equally spaced points. If it is used on a regular sample, it behaves exactly as a traditional Simpson integrator.
