Class EnhancedSimpsonIntegrator

java.lang.Object
  extended by org.jscience.mathematics.analysis.quadrature.EnhancedSimpsonIntegrator
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
