利用分块矩阵以及其子块矩阵的特征值之间的关系,得到一类分块下三角形矩阵特征值的扰动界,所得结论推广了Wielandt-Hoffman定理和先前的结果.
By using the relation the perturbation bounds for conclusions generalize the Wie between the eig eigenvalues of envalues of the block matrix and a class of triangular matrice landt-Hoffman theorem and previous results. the sub-block Matrix, s are obtained. The
