[SciPy-user] Correct syntax for optimize.fmin_powell

Can someone point me to the correct syntax for optimize.fmin_powell
when the objective function takes side arguments. I have tried every
possibility I can think of, most of which work fine for
optimize.fmin, but keep getting error messages, mainly due to an
incorrect number of arguments. I have looked at the source, but that
hasn't helped.
I am typically trying to something like
def test_arg((x,y),(a,b)):
return (x-a)**2 + (y-b)**2
min = optimize.fmin_powell(test_arg,(1.0,2.0), ((5.0,6.0),))
This works with optimize.fmin, but fails with optimize.fmin_powell.
Thanks
Jaroslav
