We denote by Q(A) the set of all matrices with the same sign pattern as A. A matrix A has signed null-space provided there exists a set S of sign patterns such that the set of sign patterns of vectors in the null-space of Ã is S for each Ã is an element of Q(A). Some properties of matrices with signed null-spaces are investigated.
