Apologies if this appears twice as I also sent this yesterday - it hasn't shown up on the archive yet and I'm not sure if it got through.
GWP Hello, I'm trying to use the gsl to solve an ode which I can't define simply. My aim is to define the ode by calling inside the int (* function) (double t, const double y[], double dydt[], void * params) function other functions. These functions will need to take in as parameters t, and y(t). I've tried doing this by inside the int (* function) (double t, ... function converting y[0] into a double and passing the resulting value and the value for t to the other functions. My attempt must be wrong however as the result for the conversion of y[0] is nan on all but the first call to int (* function) (double t, ... . Is it possible to do what I'm trying to do, and if yes, how would it be done? Thanks for reading this and any help you can give, GWP _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
