Hi, I am trying to write a little code to create a smart 'ndsolve' routine like that in mathematica. I will try to interface with gsl ode_solver. I am less than week old python newbie :), so more experienced people please help me out... Let's take the following as an example, defining our function

Hi, @rajeev Thanks for the gsl link. I am aware of it. gsl is interface is really horrible :). We need something way smarter. @dumont We can surely take into account the stiff solvers. I am interested to write such codes. On Mar 28, 2:19 am, Rajeev wrote: > Hi, > sage has gsl as one of the inclu
