Hello, my friend:
Recently, I encounter a MATLAB program problem on the propagation of the soliton in
dielectric . I find that many people use a beam propagation method ( split-step fft ) in order
to simulate this procedure. But I cann't get incorrect result.
I am eager to...
My question
First, thank you .but if the solution of the equation (U) is a complex number, how to separate the "u" into the two condition:(1) U>0; (2) U<0.
It is a nonliear Partial differential equation . you can find it in the appendix.
If you have some good idea about this equation ,ok ,please reply to me .thanks!
