public class InfinityMidPointQuadratureMatrixIntegrator
extends QuadratureMatrixIntegrator<InfinityMidPointMatrixQuadrature>

Computes matrix (multivariate) 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: InfinityMidPointQuadratureMatrixIntegrator integrator1 = new InfinityMidPointQuadratureMatrixIntegrator(-5.0, 2.0, listener); InfinityMidPointQuadratureMatrixIntegrator integrator2 = new InfinityMidPointQuadratureMatrixIntegrator(2.0, 1e99, listener); double integral = integrator1.integrate() + integrator2.integrate();
