I don't see that. Is it possible you read it wrong? In the help system
I'm using (v5.1.2) it says that derivatives are computed automatically
by finite differences. I agree that the documentation is poor. For example,
it states that INFORM=1 corresponds to fractional changes in the function
being smaller than EPSTOP for NSTOP consecutive iterations. However NSTOP is
nowhere defined.
