• H-matrices
• Schur complement
• M-matrices
• Diagonal dominance
• P-matrices
• Pivoting

We analyze a class of matrices generalizing strictly diagonally dominant matrices and included in the important class of H-matrices. Adequate pivoting strategies and the corresponding Schur complements are studied. A new class of matrices with all their principal minors positive is presented.
