    Perturbation Analysis on Symmetric Indefinite and Generalized Semi-Positive Matrices

    • The perturbation of a generalized LDL~T factorization with symmetric indefinite coefficient matrix G is proposed.Then the perturbation of the equation GX=b is given.The generalized semi-positive definite matrix is also discussed.
