Expokit is an efficient Fortran implementation for computing the matrix exponential, or rather, its action on a vector, for large sparse matrices. This can also be understood as computing the solution of a system of linear ordinary first order differential equations. This package provides an R-interface to some of the Fortran subroutines from Expokit.

The Fortran package was developed by Roger B. Sidje, see http://www.maths.uq.edu.au/expokit/. Niels Richard Hansen adapted the package for use with R and wrote the R interface. Permission to distribute the Expokit source under GPL was obtained from Roger B. Sidje.
