In this paper we consider a simple scaling condition for a special subclass of H−matrices and we present applications of this condition in eigenvalue localization for Schur complements of matrices in this subclass. Spectra localizations for the Schur complement matrix are based on the construction of the diagonal scaling matrix for the given H−matrix and use only the entries of the original matrix.
