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 作为应用,还利用新得出的标准型对这2类双结构矩阵特征值问题发展了结构算法,其中对第一类双结构矩阵特征值问题发展了只用实运算的结构算法。
