com.irurueta.numerical.integration.ExponentialMidPointMatrixQuadrature

public class ExponentialMidPointMatrixQuadrature
extends MidPointMatrixQuadrature

This is an exact replacement for MidPointMatrixQuadrature, except that upper limit is assumed to be infinite. It is assumed that the function decreases exponentially rapidly at infinity.
