The comparison of three kinds of Newton methods in solving nonlinear equations
【摘要】 首先介绍了求解非线性方程组的Newton法、简化Newton法和修正的Newton法,并给出了各自的实现算法;然后采用VC++编写了实现上述三种算法的源程序;最后通过一个实例,分析并比较了三种算法的计算量和收敛速度。
【Abstract】 Newton method、simplied Newton method and modificatory Newton method are introduced in this article firstly,and their algorithm are presented respectively;Then,the source code of three algorithms above mentioned are compiled by VC++;Finally,the calculative scalar and the convergent speed are analyzed and compared for the algorithm by an example.
