EigenDecomposition.getD介绍

[英]Gets the block diagonal matrix D of the decomposition. D is a block diagonal matrix. Real eigenvalues are on the diagonal while complex values are on 2x2 blocks { {real +imaginary}, {-imaginary, real} }.
[中]获取分解的块对角矩阵D。D是块对角矩阵。实特征值在对角线上，而复值在2x2块{{Real+virtual}，{virtual，Real}上。
