一种可调且单调的S型函数插值法

摘要

介绍一种可调且单调的S型函数插值法。在实际问题中，一般的样条 插值函数不满足单调递增性质。本文介绍的分段S型函数插值法可满足单调递增性质，又具 有光滑性质，且从全局的角度减少函数的波动性和计算量。%With subdivision S type functions,a new interpolati on method is studied.In general,spline interpolation functions don't fit the nee d of monotony property.New functions not only have the smooth and monotony incre asing property,but also can reduce its fluctuation and calculation.
