This paper presents an efficient numerical method for the computation of eigenpair derivatives for the real symmetric eigenvalue problem with distinct eigenvalues. The method has a very simple algorithm and gives an exact solution because no iteration scheme is used. The eigenpair derivatives can be
A fast efficient algorithm may be used for integrating very large (n >> 10) stiffdifferential equations of the type R = Ax + Bu + f(x, t), x(t0) = x0, wh ere f(x, t) has a small Lipschitz constant. Summary--An algorithm for integrating high dimensional stiff nonlinear differential equations of the
