| Abstract: | We consider the use of the Restricted-Denominator (RD) rational Arnoldi method for the computation of the core functions of exponential integrators for parabolic problems. Reliable and easy-to-use a-posteriori error bounds are presented. (© 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim) |
