From: John Harrold on 16 Jul 2010 16:08 Howdy Folks, I'm trying to help someone convert a ODE based model from one software package to another. The other software package uses the LSODA solver [1]. Her system is pretty stiff, and I could get it to solve for one set of parameters using ode15s, but I had to switch to ode23s to get it to solve with a different set of parameters. Based on her experience with the LSODA solver, it seems more robust. I was wondering if there was anyone out there using this solver in Matlab with an implementation I could use for comparison purposes. [1] https://computation.llnl.gov/casc/odepack/odepack_home.html
