com.irurueta.numerical.integration.UpperSquareRootMidPointMatrixQuadrature

public class UpperSquareRootMidPointMatrixQuadrature
extends MidPointMatrixQuadrature

This is an exact replacement for MidPointMatrixQuadrature, except that it allows for an inverse square-root singularity in the integrand at the upper limit b.
