    odeint function in SciPy

    I was wondering what numerical method the odeint function is based on.
    I have checked the documentation but couldnt find anything. I would be
    very grateful if someone could answer this question for me, I'm not
    looking for a heavy mathematical answer!

    Cheers!

      You could also check the source or ask on the appropriate mailing list.

      But since if you do the latter, you'll still get me, odeint uses ODEPACK.

          Thanks for the link! I think it has the information I want in it (the
          numerical method eg Runge-Kutta). However I am not sure which of the
          solvers listed within that file is used by odeint.

          All I want to achieve is to write a few lines on the mathematical
          method used by odeint for my college project.

          Many Thanks

                  Thanks for your help! I don't suppose you happen to know what order
                  this method is?

                      If your answer isn't in the docs I pointed you to or in the source, then
                      I don't know it. Happy hunting.
