PFQAD

 
Computes integral on (X1,X2) of product of function and the ID-th derivative of
B-spline which is in piecewise polynomial representation.
 
Classes  :  E3a3 .   Quadrature involving fitted functions
            H2a2a1 . 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 via user-defined procedure
            K6a3 .   Quadrature involving fitted functions
