BSPEVAL:  Evaluate B-Spline at parametric points


 Calling Sequence:

   p = bspeval(d,c,k,u)

    INPUT:

       d - Degree of the B-Spline.
       c - Control Points, matrix of size (dim,nc).
       k - Knot sequence, row vector of size nk.
       u - Parametric evaluation points, row vector of size nu.
 
    OUTPUT:

       p - Evaluated points, matrix of size (dim,nu)
