Abstract
A rational cubic interpolating spline with quadratic denominator was constructed by Gregory and co-workers. This paper deals with the properties of the interpolation and local shape control of the interpolant curves. The methods of value control, convex control and inflection-point control of the interpolation at a point are developed. Some numerical examples are provided to illustrate these methods.
