[ascl:2208.009] LeXInt: Leja Exponential Integrators

LeXInt (Leja interpolation for eXponential Integrators) is a temporal exponential integration package using the method of polynomial interpolation at Leja points. Exponential Rosenbrock (EXPRB) and Exponential Propagation Iterative Runge-Kutta (EPIRK) methods use the Leja interpolation method to compute the functions. For linear PDEs, one can get the exact solution (in time) by directly computing the matrix exponential.
