Hi all.
I am studying the use of split step Fourier method to solve NLS-typed equations.
One problem is that, for this type of equations:
iAt+Axx+|A|^2A+C=0, where C is a constant
How shall I implement the split step Fourier method?
I find no where to put my constant C because it is not multiplied with A, so I can't really put it in the linear or nonlinear part, is it?
Any idea? Thanks

because its a constant, it shouldn't really matter where you put it. ie. in the linear or nonlinear part.

thats at least my understanding...
