BSQAD

 
Computes the integral of a B-spline from X1 to X2. The B-spline must be in B
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
