摘要
本文给出了一个求超越方程实根的新的两点格式xk+1=xk-xk-xk-13f(xk)-4fxk+xk-12+f(xk-1)f(xk),它集弦割法和抛物线法的优点于一身,具有更快的收敛速度,且收敛阶为二阶.
This paper gives a new two point interation method of approximating solutions of the transcendental equation f(x)=0. The iteration algorithm is given by x k+1 =x k-x k-x k-1 3f(x k)-4fx k+x k-1 2+f(x k-1 )f(x k) The order of convergence will be p =2.
