Positivity preserving interpolation by using rational quartic spline

Positivity preserving interpolation by using rational quartic spline

In this study, a new scheme for positivity preserving interpolation is proposed by using C1 rational quartic spline of (quartic/quadratic) with three parameters. The sufficient condition for the positivity rational quartic interpolant is derived on one parameter meanwhile the other two are free para...
