As one of the applications , structure - preserving algorithms for the eigenvalue problems of those 2 kinds of doubly structured matrices are developed by the exploitation of the newly derived canonical forms , in which algorithms using real operations only are developed for the first kind of doubly structured matrix 作為應(yīng)用,還利用新得出的標(biāo)準(zhǔn)型對這2類雙結(jié)構(gòu)矩陣特征值問題發(fā)展了結(jié)構(gòu)算法,其中對第一類雙結(jié)構(gòu)矩陣特征值問題發(fā)展了只用實運算的結(jié)構(gòu)算法。
