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.
