com.irurueta.numerical.integration.SimpsonMidPointQuadratureIntegrator

public class SimpsonMidPointQuadratureIntegrator
extends SimpsonIntegrator<MidPointQuadrature>

Computes function integration by using Simpson's rule and mid-point quadrature. Simpson's method is an optimization of Trapezoidal quadrature integrator. This type of integrator will in general be more efficient than Trapezoidal quadrature integrators (i.e., require fewer function evaluations) when the function to be integrated has a finite fourth derivative (i.e., a continuous third derivative).
