我们首先描述了一个算法,减少了matrixA的块对角的形式,只使用良好的条件变换。然后从所得的块对角矩阵中进行A的谱性质。我们特别表明,频谱肖像的A可以得到便宜的块对角矩阵。
We first describe an algorithm that reduces a matrixAto a block diagonal form using only well conditioned transformations. The spectral properties ofAare then carried out from the resulting block diagonal matrix. We show in particular that the spectral portrait ofAcan be obtained cheaply from that of the block diagonal matrix.
