Solve a non linear differential equation systems with only boundary conditions
7 views (last 30 days)
I am currently trying to solve a differential equation of the form :
function dy= myfun(r,y)
Only , I know from my physical problem only what happened on the edge (at r2=10mm). I tried then to use bvp4c, but I have the feeling they would need anyway at least one initial condition.
where val1=y1(0) et val2=y2(r2) However, I would like to set val1=y1(r2) and val2=y2(r2) instead!

You have a system of two first order differential equations so you need just two boundary conditions. I would guess that specifying y1(r2) and y2(r2) is fine.
What kind of problem are you running into? If you post your complete example, we might be able to help.
