4) finery matrix
优良矩阵
1.
A is said be an inverse finery matrix if A is nonsingular and its inverse is a finery matrix, Let A be a finery matrix of order n, In this paper we obtainthat A is an inverse finery matrix if and only if det A>0 or for each a ∈ Q_(rn),1≤r≤n-1, detA[a]det A(a)<0 when det A<0, which provides an answer to the open problem raised by TuBoxun in[3].
如果Ａ是非奇异的，且它的逆是优良矩阵，则称Ａ是逆优良矩阵，本文证明了Ａ是逆优良矩阵的充分必要条件是ｄｅｔＡ＞０或对每个ａ∈Ｑ＿（ｒｎ），１≤ｒ≤ｎ－１。
6) precedence matrix
优先矩阵
