[Numpy-discussion] argmin and argmax without nan

 hi,
   is there any way to get argmin and argmax of an array w/o nans?
   Currently I have
   >>> from numpy import *
   >>> argmax([10,nan,100])
   1
   >>> argmin([10,nan,100])
   1
   But it's not the values I would like to get.

   The walkaround I use: get all indeces of nans, replace them by -inf,
   get argmax, replace them by inf, get argmin.
   Is there any better way? (BTW, I invoke argmin/argmax along of a
   chosen axis)
   D.
