方程求实根的四分试位算法

Quartile division and regular-falsi-iteration algorithm of solving the equation

给出方程f(x) =0求实根的四分试位算法。不管是否重根 ,只要f(x)连续有实根且初值合适 ,都能较快得到理想的近似根。表 4参

Quartile division and regular falsi iteration algorithm of solving the equation f(x)=0 is given out.Whatever repeated root is,a good approximate real root is quickly got by it if f(x)=0 has a continuous real root and reasonable initial value.
