Dear Chiara,

I like too your idea on exponential integrators and I would be available as co-mentor. About the other project on matrix functions, it would be completely different. In fact, in exponential integrators it is required only the action of the matrix exponential to a vector. To this purpose, one of the best (fast, reliable) methods available is the one developed by Nick Higham (Computing the action of the matrix exponential with an application to exponential integrators). He very recently made his code available with a free license

https://github.com/higham/expmv

Of course, this is just a small ingredient of an exponential integrators package. Anyway, I'm pretty sure it does not work in Octave as is. Can you please verify and fix it (or report what does not work and why)?

Moreover, the two methods you mentioned (exp. Euler and exp. Rosenbrock-Euler) are very basic methods with no adaptive time step. Can you find the relevant references for exponential integrators?

Best regards,

Marco

Dear Carlo and Marco,

thank you for your consideration on my proposal.

I read the discussion about matrix functions and now I look at the Nick Higham code, I'll let you know as soon as possible.

Could you give me some information about how to submit an official application for GSOC about the exponential integrators project?

Thank you,

Best regards

Chiara
