the numerical solution to a problem involving a nonlinear partial differential equation of the form below
$u_t + uu_x + u_{3x} − u_{5x} = 0$
$u(x, 0) = f (x) , x ∈ R$
which is called Kawahara equation?
I have this adomian solution maple code to solve it but it brings me lots of error
have you any idea?
