Thanks for *vdelecroix* for redirecting my post to this group, and for all useful posts. It seems that my last sentence about Nestlists -to some extent- misleads my friends. The main point I want to know is: what is a simple way to create a large system of equations and initial conditions, such that they can be used as input for ODE solver functions in Sage. The equation is i(d/dt)Psi(t)=H(t).Psi(t)
(Schrodinger's equation), where H(t) (the large matrix) and Psi(0) (the large vector of initial conditions) are given, and Psi(t) is the vector of unknown functions.
