In what order would you like argsort to sort the values -inf, nan, inf?
Ideally, -inf should sort first, inf should sort last and nan should raise an exception if present. -tim
In numpy 1.0b1 nan is always left where it began:
EXAMPLE 1
x
matrix([[ inf], [ -inf], [ nan]])
x[x.argsort(0),:]
matrix([[ -inf], [ inf], [ nan]])
EXAMPLE 2
x
matrix([[ nan], [ inf], [ -inf]])
x[x.argsort(0),:]
matrix([[ nan], [ -inf], [ inf]])
I would like nan to be in the middle between -inf and inf.
