com.irurueta.numerical.integration.LowerSquareRootMidPointMatrixQuadrature

public class LowerSquareRootMidPointMatrixQuadrature
extends MidPointMatrixQuadrature

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