May 20, 2012 · I would like to create a 3D array in Python (2.7) to use like this: distance[i][j][k] And the sizes of the array should be the size of a variable I have. (nnn) I tried using: distance = …

New at Python and Numpy, trying to create 3-dimensional arrays. My problem is that the order of the dimensions are off compared to Matlab. In fact the order doesn't make sense at all. …

In cases like that, I usually append all elements to a one-dimensional, flat list, and then, when I am finished reading, convert it to a numpy array and reshape it to the correct, three …
