迭代【ite口te;.什pa”11。] 重复应用某种数学运算的结果.这样,如果 y=f(x)三f,(x)是x的函数,则函数 fZ(x)=f[f;(x)」,…,f。(x)=f【f。一:(x)』顺次称为f(x)的二次,…,n次迭代(j记m记).例如,令f(x)=x‘,就得到 fZ(x)=(x“)一x·,, f。(x)=(x‘’一’)“=x““.指标”称为迭代的拳攀(Cxponent),而从f(‘)转移到fZ(x),f,(x),…也称为迭代(ite瑙如n).可以对某种函数类定义具有任意实指数甚至复指数的迭代.迭代用于通过迭代方法求解各种方程或方程组.详见序列逼近法(seq谬ntialappro劝na石on,兹心山记of).
