摘　　要：In this paper,it is given that the new equivalent definition of level-k (r1,r2, …,rk)-cir culant matrices of type (n1,n2,…,nk) in [1] and we give the explicit expression of its the eigenval ues and four methods of discriminations its nonsingularity by utilizing only parameter r1,r2, …,rk and elements of the first row of the sorts matrices.

关 键 词：level-k (r_1  r_2  …  r_k)-circulant matrices of type(n_1  n_2 …  n_k) NONSINGULARITY
