[Numpy-discussion] Fwd: np.unique for one bi-dimensional array

2012-07-25 Thread Giuseppe Amatulli
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.
