连续函数的一种指数逼近方法

An Exponential Approximation to Continuous Function

该文建立了半无穷区间上函数的一种指数逼近算法及误差估计。该法收敛速度快,能保证一致收敛且精度达到并超过0.1％,该精度被认为是当前现有指数逼近方法的极限精度。

A numerical method of exponential approximaton tocontinuors function defined on semi--infinite inteval is presented and itserror estimation is also given. The method has fast and uniformconvergence. In practice its accuracy is about 0.1%, whlich is nowbelieved the limit accuracy of all the methods now available.
