All Implemented Interfaces:

SampledMappingNDIntegrator

public class TrapezoidNDIntegrator
extends java.lang.Object
implements SampledMappingNDIntegrator

This class implements a trapezoid integrator.

A trapezoid integrator is a very simple one that assumes the function is linear over the integration step.

Description copied from interface: SampledMappingNDIntegrator

Integrate a sample over its overall range

Specified by:

integrate in interface SampledMappingNDIntegrator

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
