摘要
We construct a rational biquadratic spline interpolating an arbitrary function and its gradient at vertices of a rectangular grid of a domain Omega = [a, b] x [c,d]. The introduction of the control net allows to give sufficient conditions ensuring the bimonotonicity or the biconvexity of the underlying surface.
