Hi, would like to take eliminate a specific number in an array and its correspondent in an other array, and vice-versa.
given a=np.array([1,2,4,4,5,4,1,4,1,1,2,4]) b=np.array([1,2,3,5,4,4,1,3,2,1,3,4]) no_data_a=1 no_data_b=2 a_clean=array([4,4,5,4,4,4]) b_clean=array([3,5,4,4,3,4]) after i need to calculate unique combination in pairs to count the observations and obtain (4,3,2) (4,5,1) (5,4,1) (4,4,2) For the fist task i did a_No_data_a = a[a != no_data_a] b_No_data_a = b[a != no_data_a] b_clean = b_No_data_a[b_No_data_a != no_data_b] a_clean = a_No_data_a[a_No_data_a != no_data_b] but the results are not really stable. For the second task The np.unique would solve the problem if it can be apply to a two arrays. Any idea? thanks in advance Giuseppe -- http://mail.python.org/mailman/listinfo/python-list
