我想查看译文中含有：的双语例句  zero pattern
 An upper bound and a lower bound for α0 are given such that for for α≤α0, whereB is a nonnegative matrix and satisfies that for any positive constant β,βI+B is a power invariant zero pattern matrix. Their appearance is related to small but typical deviations from the zero pattern predicted by dual models. There are qualitative discrepancies with the zero pattern of Odorico's Linear Zero Model. In this paper we introduce a new, specialized type of matching which we call uniquely restricted matchings, originally motivated by the problem of determining a lower bound on the rank of a matrix having a specified zero/ non-zero pattern. An interesting property of the feasible set imposes a zero pattern for the solution. 更多 A real matrix A is said to have a signed generalized inverse if the sign pattern of its generalized inverse A + is uniquely determined by the sign pattern of A.In this paper,on the base of researches about signed generalized inverses,we further study the sign pattern and zero pattern of A + where A is a matrix having signed generalized inverse.We also apply these results to obtain some property of least spuare sign solvable linear systems in terms of matrices having signed generalized inverses. 若一个实矩阵A的广义逆A+的符号模式由A的符号模式所唯一确定 ,则A被称为广义逆符号唯一 .在关于广义逆符号唯一矩阵的一些现有结论基础上 ,进一步研究了当矩阵A为广义逆符号唯一时 ,A+的符号模式和零位模式的具体特征 .还讨论了当A不为广义逆符号唯一时 ,与A有相同符号模式的矩阵广义逆族在某些位置上所能取到的不同符号情况 ,并且给出了这一结果在讨论线性方程组的最小二乘符号可解性中的一个应用 . Fiedler and Markham introduced the L t -Matrices,and paritioned the set Z n of all n×n Z -matrices into n+1 classes: L 0,L 1,...,L n .In this paper we use the associated digraph of a Z-matrix to investigates the combinatorial properties of Z-matrices whose diagonal entries are all zeros(with zero diagonal).We first proove that a Z-matrix A with zero diagonal is a L t -matrix if and only if the least length of the circuits of the associated digraph of A is t+1 .Then we decribe...
