VODE solver....supplying Jacobian

HI
I am trying to solve a relatively small number of stiff
First order ODE's. To do this I am trying to use
VODE.

Though this program can calculate the Jacobian, the
instructions suggest that, if possible, it is supplied.
Is there any reason why a Jacobian that I supply would
be better than letting the code calculate one itself?

Also, what are the advantages of banding the Jacobian
and why would I want to do this?

Thanks in advance

Jason
