Hi Zach and Derek,
thank you very much for your quick and clear answers. Of course the third
parameter is the out array, I was just being very stupid! (I had read the
documentation though, but somehow it didn't make it to my brain :-) Sorry...

> The optional third parameter to numpy.minimum is an "out" array - an
> array to place the results into instead of making a new array for that
> purpose. (This can save time / memory in various cases.)
