I definitely second this comment. Using arrays when you are trying to append a lot of data is using the wrong data format. And the code is so much more readable with lists.
Thank you, I will consider it, Next thing, I have A_Idx = array([1, 0]) and B is a matrix. How would I select the four elements in B indicated by "meshgrid(A_Idx)", that ist: B[1,1], B[1,0], B[0,1], B[0,0] In Matlab you would simply use B(A_idx, A_idx) whereas in NumPy B[A_Idx, A_idx] returns B[1,1] and B[0,0] only. I read that A.take(A_idx).take(A_idx, axis = 1) should work but it doesn't. Thank you, David
