【摘要】In this article,we discuss singular Hermitian matrices of rank greater

or

equal

to

four

for

an

inverse

eigenvalue

problem.Specifically,we look into how to generate n by n singular Hermitian matrices of ranks four and five from a prescribed spectrum.Numerical examples are presented in each case to illustrate these scenarios.It was established that given a prescribed spectral datum and it multiplies,then the solubility of the inverse eigenvalue problem for n by n singular Hermitian matrices of rank r exists. 【总页数】5页(P.119-123)
