java.lang.Object
  extended by org.jscience.mathematics.analysis.quadrature.TrapezoidNDIntegrator
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:
