Class RombergInfinityMidPointQuadratureIntegrator

com.irurueta.numerical.integration.RombergIntegrator<InfinityMidPointQuadrature>

com.irurueta.numerical.integration.RombergInfinityMidPointQuadratureIntegrator

public class RombergInfinityMidPointQuadratureIntegrator
extends RombergIntegrator<InfinityMidPointQuadrature>

Computes function integration by using Romberg's method and Infinity mid-point quadrature.

If you need to integrate from a negative lower limit to positive infinity, you do this by breaking the integral into two pieces at some positive value: RombergInfinityMidPointQuadratureIntegrator integrator1 = new RombergInfinityMidPointQuadratureIntegrator(-5.0, 2.0, listener); RombergInfinityMidPointQuadratureIntegrator integrator2 = new RombergInfinityMidPointQuadratureIntegrator(2.0, 1e99, listener); double integral = integrator1.integrate() + integrator2.integrate();
