Error estimates for Krylov subspace approximations of matrix exponentials Academic Article uri icon


  • The paper develops a better upper estimate of the error for the Krylov subspace approximations to the exponential of a large matrix than that given by Gallopoulos and Saad (1992). This approach is based on Chebyshev series approximation.
