Exponential Integrator in MATLAB?

Hi all,

I wanted to ask if anyone happens to know of a package/code in MATLAB which solves equations utilising exponential integration methods. These seem to be reasonably well known methods that happen to be suitable for the problem that I have to solve.

I have found one called EXPODE which is a MATLAB toolbox, however I can't find the code for that anywhere. I have also looked into File Exchange and I have only found a meshfree exponential integrator, however these have to do with partial differential equations.

Thanks for your help in advance,

K.

@KostasK Hi, did you find EXPODE toolbox anywhere? I am trying to find it, too. So far without any success.

Hi Konstantinos,

There is no specific method to solve Ordinary Differential Equations using Exponential Integration methods in MATLAB as of now apart from the general method dsolve in the Symbolic Math Toolbox. This might be included in a future release.

The EXPODE toolbox that you are referring to is built on top of MATLAB functions.
