Thanks guys, I think my wording belies my understanding of the problem somehow. I have a very large deal.ii code that solves a highly nonlinear multicomponent PDE, and is working quite well. I do know how to do what I need in matlab, and a number fo different software. For example, I can exponentiate a matrix in LAPACK, though have never h
