[Numpy-discussion] proposal: min, max of complex should give warning

I don't work with complex numbers, but just sampling what others do:
Python: no ordering, results in TypeError
Matlab: sorts by magnitude
http://www.mathworks.com/help/matlab/ref/sort.html
R: sorts first by real, then by imaginary
http://stat.ethz.ch/R-manual/R-patched/library/base/html/sort.html
Numpy: sorts first by real, then by imaginary (the documentation link
below calls this sort 'lexicographical' which I don't think is
correct)
http://docs.scipy.org/doc/numpy/reference/generated/numpy.sort.html
I would think that the Matlab sort might be more useful, but easy
enough by using the absolute value.
I think what Numpy does is normal enough to not justify a warning, but
leave this to others because as I pointed out in the beginning I don't
work with complex numbers.
Kindest regards,
Tim
