However, such complex symmetric systems are usually much more difficult to be solved because of the property of non-Hermitian therefore, efficient numerical methods for the solution of complex symmetric systems are demanded. In this study, we proposed an iterative method called COMINRES-QLP which is specially designed for complex symmetric linear systems. Moreover, we proposed a new stopping criterion which could be very useful in practical computations when the condition number of the coefficient matrix is unknown.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.140 No.12 （2020）本誌掲載ページ: 832-841 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/140/12/140_832/_article/-char/ja/
