摘要
Landweber迭代法对于求解大规模问题是十分有利的,但是,Landweber迭代序列收敛速度是相当慢的.给出了一种新的Landweber迭代格式,能够大大加快收敛速度.还将Landweber迭代法应用于数值微分问题,将数值微分问题转化为一个特殊的第一类Fredholm积分方程的求解问题.
Landweber escalator method for solving the large-scale problem is very beneficial. Therefore,A escalator sequence of the Landweber refrains from rash action the speed is very slow. This text give a format of a kind of new Landweber escalator format, can speed to refrain from rash action the speed consumedly. Return to apply a method of the Landweber escalator method in the number differential calculus problem, Solve the number differential calculus problem conversion for a special and the first distance with square integral calculus of Fredholm problem.
