 Abstract
We denote by (A) the set of all real matrices with the same sign pattern as a real matrix A. A matrix A is an SN-matrix provided there exists a set S of sign pattern such that the set of sign patterns of vectors in the -space of is S, for each . Some properties of SN-matrices arc investigated.
