迭代不动点稳定性的一种判定

Test for Stability in Interation of Fixed Point

引进迭代稳定域的概念，引用的微分中值定理和矩阵的范数，讨论了数值分析中映射不动点迭代过程的稳定性，并给出了一种求迭代稳定域的方法。这从某种意义上简化了［１］中关于误差分析过程。

Introducing the stable range,using the mean value theroem and norm of matrix,a test of stability of interation is obtained, the discussing of error analysis in [1] is simplified.
