摘要 构造了一种分母为二次的有理三次插值函数.它是C1连续的.在给定的插值数据条件下,通过调整插值函数中的参数,给出了插值曲线的保凸方法和该方法得以实现的条件. A rational cubic interpolation function with quadratic polynomial denominators is constructed . The interpolation function is continuous. A method is presented for controlling the convexity of interpolant curves. The conditions for the interpolating curves to be convex in the interpolating intervals are derived.
