Hii Friends,
I am pretty new to matlab. Could anyone suggest me a wayt o solve the following nonlinear scrodinger equation
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/165748/image.jpeg)
In this equation, the terms B1,B2, alpha, gamma can be considered as constants.
z and t are variables. i is imaginary term = sqrt(-1).
I would like to see how A evolves with z(distance) and time(t).
the intial A can be considered as a gaussian or a plane wave.
Is there any other information that is required?

This Nonlinear Schrodinger Equation is commonly used as a basic propagation model equation in optical fiber communication systems. In this research field, many researchers use split-step fourier method (SSFM) to numerically solve this equation.

More details of this method can be found in the textbook "Nonlinear Fiber Optics" written by Dr. Agrawal. Of course, MATLAB can do it !

Hi every one. well I have a problem in building code for numerical scheme of a linear discret equation using finite dieference method.
My eqution is
E*A(i)= P*cos(w*i)*A(i) + Q*( A(i-1) +A(i+1) ) where w,Q are fixed constants and i is interger index on the amplitud A
P=[0 : 6] . I need to plot E=f(P)
anybody can help me? plzzz
