摘要
给出n阶半正定Hermite矩阵配乘特征值反问题可解的三组必要条件。当n=2时,这些必要条件同时是该反问题可解的充分条件。
Necessary conditions for the solvability of multiplicative inverse eigen-value problem over nxn semipositive definite Hermitian matrices are studied. The necessary conditions presented in this paper turn to be characterizations when n=2.
