实运算 meaning in English

real operation

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。
