LeXInt: Package for Exponential Integrators employing Leja interpolation
arXiv:2208.08269 · doi:10.1016/j.softx.2022.101302
Abstract
We present a publicly available software for exponential integrators that computes the functions using polynomial interpolation. The interpolation method at Leja points have recently been shown to be competitive with the traditionally-used Krylov subspace method. The developed framework facilitates easy adaptation into any Python software package for time integration.
