dx1/dz=0.5*beta2*x1*x4 evolution of amplitude

dx2/dz=-beta2*x5 evolution of position

dx3/dz=-beta2*x3*x4 evolution of width

dx4/dz=-4*beta2/x3^4+beta2*x4^2-gamma*x1^2/x3^2

dx5/dz=0

beta2 is dispersion of velocity group

gamma is nonlinear coefficient

Consider taking a look at some of the other questions asked about implementing a 4th order Runge-Kutta in MATLAB.
