摘要
本文讨论基于Liapunov稳定性理论的一个渐近根轨迹迭代公式,弦割法和Newton法是它的两个特例.其显著特点是简单,经济,高效。
This paper proposes an asymptotic root locus itration method which is based on Liapunov stability for solutions of equations in one variable. In special cases it becomes the secant method and Newton method. Its outstanding characteristics are simple, economical and efficient.
