Split Step Fourier Method

  1. Feb 4, 2008 #1
    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...
