org.spaceroots.mantissa.quadrature.scalar.TrapezoidIntegrator

All Implemented Interfaces:

SampledFunctionIntegrator

public class TrapezoidIntegrator
extends java.lang.Object
implements SampledFunctionIntegrator

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: SampledFunctionIntegrator

Integrate a sample over its overall range

Specified by:

integrate in interface SampledFunctionIntegrator

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

FunctionException - if the underlying sampled function throws one
