Computable upper error bounds for Krylov approximations to matrix exponentials and associated -functions
Tobias Jawecki, Winfried Auzinger, Othmar Koch
An a posteriori estimate for the error of a standard Krylov approximation to the matrix exponential is derived. The estimate is based on the defect (residual) of the Krylov approxi…
