Based on Parameter Equation Function Rational Spline Interpolation with the Shape Preserved


A rational cubic spline function (3/2) involving two shape parameters is presented, and is applied to the interpolation problem with the data that its type is parameter equation function. Based on it, we deduce a sufficient condition for sign preserving and monotonicity preserving. Thus by adjusting the shape parameters, it can interactively modify the… (More)
