MFNEXPOKIT#
MFNEXPOKIT = “expokit” - An Arnoldi method tailored for the matrix exponential, as implemented in the Expokit package.
Notes#
This solver implements the method of Expokit natively in SLEPc, rather than interfacing to the original Expokit software [Sidje, 1998].
The method uses Arnoldi relations to compute \(\exp(\alpha A)v_\mathrm{last}\) for several time steps, where \(\alpha\) is the time step size.
