[SciPy-User] scipy.optimize fmin error

Thanks,
That does the trick !!!
That's what I call erosion, took me too much time to implement it in
python, comparing to matlab, and just out of frustration I didn't see
that little error !

Our university is too much Matlab ($%^!# ) centric, no one to ask
around unfortunatly....

BTW, feel free to use this code (with the correction of course) as a
real world example - it's a tracer test analysis made in a ground
water test site here in southern Germany.

Also, I felt python is much faster:
With matlab optimization of the problem took:

Elapsed time is 0.212064 seconds (for first run... further runs where
much better)

With python (first run):
took  0.0125770568848 sec to run

Which is a nice bonous !

Many thanks,
P.S when I have some time in the weekend I'll put into my blog, which
already has many numpy/scipy examples !
