All Implemented Interfaces:

SampledMappingIntegrator

public class EnhancedSimpsonIntegrator
extends java.lang.Object
implements SampledMappingIntegrator

This class implements an enhanced Simpson-like integrator.

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.

Description copied from interface: SampledMappingIntegrator

Integrate a sample over its overall range

Specified by:

integrate in interface SampledMappingIntegrator

Parameters:

iter - iterator over the sample to integrate

Returns:

value of the integral over the sample range

Throws:

ExhaustedSampleException - if the sample does not have enough points for the integration scheme

MappingException - if the underlying sampled function throws one
