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.
