cvodes_rhs()

static int cvodes_rhs ( sunrealtype  t, N_Vector  y, N_Vector  ydot, void *  f_data  )

static

Function called by cvodes to evaluate ydot given y.

The CVODE integrator allows passing in a void* pointer to access external data. This pointer is cast to a pointer to a instance of class FuncEval. The equations to be integrated should be specified by deriving a class from FuncEval that evaluates the desired equations.
