[R-sig-dyn-mod] How to use the ode23tb method to solve ODE in R

[John Harrold]

Howdy Peng,

For those who may not be familiar with Matlab, here is the reference for
that solver:

https://www.mathworks.com/help/matlab/ref/ode23tb.html

It says that it's an implementation of the TR-BDF2 algorithm (hence the
tb). A two stage algorithm that uses the trapizodal rule as the first stage
and the backwards difference formula. I don't know enough to really compare
solvers in deSolve or Matlab. If you dig something up please send it my way
:). I think it might be best to figure out what this solver provides for
you and to figure out which deSolve solver will provide that. It's a
stiff/low accuracy solver.

So what are you looking for?
John
