摘要
本文提出利用样条函数计算高振荡积分,克服了高次插值的严重缺点,同时避免了利用分步积分需要计算的函数在区间端点处的高阶导数,能大幅度提高计算的精确度。
In this paper, computation of ∫~b_ af(x)sin mxdx higher oscillatory integration by using spline function is considered. It overcomes the serous defects and avoids computation of the higher derivative of function at internal terminal using integration by parts. It greatly increases the precision of computation.
