Has anyone had much joy using CONSTRAINED_MIN in idl 5.1?
First the obvious. The calling sequence in the documentation is

CONSTRAINED_MIN, Xbnd, Gbnd, Nobj, Gcomp, X, Inform

while that in the example code is

CONSTRAINED_MIN, x, xbnd, gbnd, nobj, gcomp, inform

The latter is correct.

Now the less obvious. On my first run it returns a value of the
keyword INFORM of 7, although it only documents values between -1
and 6 ! On the other hand, it apparently has found a better solution
than POWELL (my problem is currently unconstrained) in many fewer function
calls so I'm not ready to abandon ship just yet. Has anybody else
experienced anything similar?
