摘要
用蛛网迭代算法求解非线性方程,只要求函数在定义域内存在反函数;由定理及其证明可知,不动点迭代是该迭代方法的特殊情况;通过数值实验进一步证明了该方法的有效性和实用性。
Cobweb-iterative algorithm is used to solve nonlinear equations. This paper requires that inverse functions exist in the function field. The theorem can prove that fixed point iteration is a special circumstance of cobweb iterative algorithm.The effectiveness and practicality of this method are further testified by numerical experiments.
