【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。更多还原

【Abstract】 With subdivision S type functions,a new interpolation method is studied.In general,spline interpolation functions don’t fit the need of monotony property.New functions not only have the smooth and monotony increasing property,but also can reduce its fluctuation and calculation.更多还原
