review text: The paper is concerned with preconditioners for \(Z\)-matrices. In particular, the given matrix is multiplied by the preconditioner before a regular splitting. The coefficients of upper triangular matrices for this purpose are determined by the nonnegativity of the nondiagonal entries of the \(Z\)-matrix.
