Hi, would like to identify unique pairs of numbers in two arrays o in one bi-dimensional array, and count the observation
a_clean=array([4,4,5,4,4,4]) b_clean=array([3,5,4,4,3,4]) and obtain (4,3,2) (4,5,1) (5,4,1) (4,4,2) I solved with tow loops but off course there will be a faster solution. I was checking also for np.unique but i did not find how to apply for a bi-dimensional array. or Concatenate the two arrays a_concatenate=array([4_3,4_5,5_4,4_4,4_3,4_4]), then np.unique, then split again. Any other/faster solutions? In bash I usually unique command Thanks in advance -- Giuseppe Amatulli Web: www.spatial-ecology.net _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
