Hi Folks, I have array (numpy.ndarray object) with non-zero elements cumulated 'somewhere' (like a array([[0,0,0,0],[0,1,1,0],[0,0,1,0],[0,0,0,0]])) and I need sub-array with just non-zero elements (array([[1,1],[0,1]])). I can do this with iterating throught an array, but I also found some magic tricks with boolen operators in indexing and nonzero function, but it is still not clear to me, how to use it.
I am sure that this will be pretty easy for those who are familiar with this kind of array indexing and I hope I will be one of them soon :-). Thanks a lot Radek _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
