Abstract

We present a publicly available software for exponential integrators that computes the φl(z)\varphi_l(z) 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.
