文章将对求解Toeplitz线性系统的CSCS(Circulant matrix and skew circulant matrix)方法中的参数选择扩大到复数域,形成复参数的CSCS方法,讨论了复参数的CSCS迭代方法的收敛性,并从复系统的数值例子验证了复参数CSCS方法的有效性。
This paper generalizes the parameter of the CSCS(Circulant matrix and skew circulant matrix)method to the complex field,which is called a complex CSCS method,we discuss the convergence of complex CSCS method.The numerical example of the complex systems shows the complex CSCS method is effective.
