com.irurueta.numerical.integration.InfinityMidPointQuadratureIntegrator

public class InfinityMidPointQuadratureIntegrator
extends QuadratureIntegrator<InfinityMidPointQuadrature>

Computes function integration by using an 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: InfinityMidPointQuadratureIntegrator integrator1 = new InfinityMidPointQuadratureIntegrator(-5.0, 2.0, listener); InfinityMidPointQuadratureIntegrator integrator2 = new InfinityMidPointQuadratureIntegrator(2.0, 1e99, listener); double integral = integrator1.integrate() + integrator2.integrate();
