Public bug reported: Binary package hint: python-numpy
Hi there! If you have and array with complex values, and try to execute: numpy.amax(array), amax, brings a result the max number of the array, but it only search in the real part. I think that there shouldn't be result, like it happens when you call the max methods on a simple list. In [1]: import numpy as np In [2]: a_list = [1+2j, 1+3j, 2+2j,1+100j, 5+1j] In [3]: a_np = np.array([1+2j, 1+3j, 2+2j,1+100j, 5+1j]) In [4]: np.amax(a_np) Out[4]: (5+1j) In [5]: max(a_list) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/malev/<ipython console> in <module>() TypeError: no ordering relation is defined for complex numbers finally, I'm using: Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) and numpy: '1.3.0' I've tried to submit the ticket at the numpy list, but it said I didn't have the privileges. That is why I'm coming here.
