All first order. I though that if I had 4 first order equations, then I would need 8 boundary conditions for both ends of the interval for each equation. I guess you're saying that is not right?
Sorry... I need two boundary conditions for each function for a BVP, right? I only have one boundary condition per function... I thought you were saying that I could use the derivitive of the function as a boundary condition.
Just to make sure I understand...
I only have one value for each function at *one* point... (let's say L, but could be 0 for the other functions) but for the boundary at the other point (let's say 0, but other functions are not bound at 0) I can use the derivitive of the function?
These...
I have a system of spatial ODEs to solve... Actually a DAE system, but here's the issue:
The equations are vaild over a specific domain, x = 0..L
The equations are only bound at one point (thier "initial point") but at either 0 or L
f1(0)=0
f2(0)=100
f3(L)=0
f4(L)=100
