DPPQAD

 
Compute the integral on (X1, X2) of a K-th order B-spline using the piecewise
polynomial (PP) representation.
 
Classes  :  E3a3 .   Quadrature involving fitted functions
            H2a2b1 . Automatic 1-D finite interval quadrature (user need only
                   specify required accuracy) (special integrand including
                   weight functions, oscillating and singular integrands,
                   principal value integrals, splines, etc.), integrand
                   available only on a grid
            K6a3 .   Quadrature involving fitted functions
