Method used in ode15i

Question

0 个投票

Hi there, I'm using ode15i to solve a complex nonlinear implicit first order ODE-system. Now I wonder how expressiv the results I get are, so here is my question: Exactly which numerical methods does ode15i use to solve the system, resp. which are the methods used in this "variable order method"? If needed I could provide a minimal example, but my system is quite complicated so I leave it for the moment. Thanks, Michael

Did you look in the source code of ode15i.m already? Usually the sources are well documented and all required details can be found there.

Jan, thanks a lot for your quick response! Could have thought of this myself... I'll have a look in there and write if I need help in understanding the source code. In the meantime I leave this open.
