Ah, no, I actually didn't. Was depending on Google to find relevent bits
in the manual. Thanks for the tip.
Would it be valuable to have an lsode wrapper for ode15s? I was
thinking this morning that it'd be easy to implement, and I may go that
route for the project code I have to write anyhow. If you'd rather just
keep it at lsode though, then I'll forgo that approach
