com.irurueta.numerical.integration.TrapezoidalQuadratureMatrixIntegrator

public class TrapezoidalQuadratureMatrixIntegrator
extends QuadratureMatrixIntegrator<TrapezoidalMatrixQuadrature>

Computes single dimension matrix (multivariate) function integration by using Trapezoidal quadrature up to desired accuracy. This integrator should be used for general functions whose "smoothness" is unknown, but have no singularities that make an improper integral (integrands with singularities, or infinite upper or lower bounds of integration).
