Class EnhancedSimpsonIntegratorSampler

java.lang.Object
  org.spaceroots.mantissa.quadrature.scalar.EnhancedSimpsonIntegratorSampler

All Implemented Interfaces:

SampledFunctionIterator

public class EnhancedSimpsonIntegratorSampler

extends Object

implements SampledFunctionIterator

This class implements an enhanced Simpson integrator as a sample.

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.

Constructor Detail

EnhancedSimpsonIntegratorSampler

public EnhancedSimpsonIntegratorSampler(SampledFunctionIterator iter)
                                 throws ExhaustedSampleException,
                                        FunctionException

Constructor. Build an integrator from an underlying sample iterator.

Parameters:

iter - iterator over the base function

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: SampledFunctionIterator

Check if the iterator can provide another point.

Specified by:

hasNext in interface SampledFunctionIterator

Returns:

true if the iterator can provide another point.

nextSamplePoint

public ScalarValuedPair nextSamplePoint()
                                 throws ExhaustedSampleException,
                                        FunctionException

Description copied from interface: SampledFunctionIterator

Get the next point of a sampled function.

Specified by:

nextSamplePoint in interface SampledFunctionIterator

Returns:

the next point of the sampled function

Throws:

FunctionException - if the underlying function throws one

ExhaustedSampleException - if the sample has been exhausted
