Thanks for your fast response.
Yeah I know, but what I solved was
dn(t)/dt=I^5(t)+I(t)*n(t)
with a time dependent I(t).
n depends on z only due to the fact that I is depending on z, there is no direct dependence. dI(t,z)/dt I only can give for the case I(t,0).. so I just adapt these coupled...
Hey,
I need your help to solve the following set of coupled differential equations numerically.
dn(t,z)/dt=I^5(t,z)+I(t,z)*n(t,z)
dI(t,z)/dz=I^5(t,z)-α(n(t,z))*I(t,z)
where I(t,0)=I0*exp(-4ln2(t/Δt)^2) and n(t,0)=0 and n(-certrain time,z)=0. Some constant parameters I did not show...
