Indefinite QR factorization is a generalization of the well-known QR factorization, where Q is a unitary matrix with respect to the given indefinite inner product matrix J. This factorization can be used for accurate computation of eigenvalues of the Hermitian matrix A = G \* J G, where G and J are
