Newton-Raphson和substitution iteration两种算法的区别是什么?
这两种方法都在什么情况下使用?有什么特别的要求吗? If a non-linear problem has difficulty converging with the Newton-Raphson method, the successive substitution method can be used instead. The successive substitution method is slower than the Newton-Raphson method, but is generally more certain to reach convergence.牛顿迭代法和逐次迭代法(简单迭代法) 回复 2# jess
我算的是换流变压器的模型,用牛顿迭代法算不收敛,改用逐次迭代法算可以收敛,而且计算时间比牛顿迭代法要少大约1/4. 多谢楼主分享,学习了。
