function A = lotkin(n) %LOTKIN Lotkin matrix. % A = LOTKIN(N) is the Hilbert matrix with its first row altered to % all ones. A is unsymmetric, ill-conditioned, and has many negative % eigenvalues of small magnitude. % The inverse has integer entries and is known explicitly. % Reference: % M. Lotkin, A set of test matrices, MTAC, 9 (1955), pp. 153-161. A = hilb(n); A(1,:) = ones(1,n);
