What about:
   z_min=min(ravel(z0))

In [3]:Numeric.ravel?
    ravel(m) returns a 1d array corresponding to all the elements of it's
    argument.

OTOH, I am not sure, if the usage of min (which is a python builtin,
operating on sequences) does not cost some performance.
So maybe

  z_min = nx.minimum.reduce(nx.ravel(z0))

is more efficient?

Best,
