Data interpolation using c2 rational quartic spline
This study discusses the construction of new C2 rational quartic spline scheme in from the quartic numerator and quadratic denominator with three parameters. Unlike the derivation of C2 continuity for some existing splines interpolation, the proposed rational quartic spline can achieve C2 continuity...
