What does this : u(x,y)''+u(x,y)' + const = 0 >
mean ? For example, u(x,y)' may mean : - diff(u(x, y), x) , - diff(u(x, y), y), or even - diff(u(x, y), x, y). Which one do you mean ? You may also have a look at desolve? or desolve_system? for analytical solutions, and desolve_rk4? for numerical integration.
