I am attempting to create 2D arrays which are offset copies of a given starting array. For example if I have a 2D array like this:
have any ideas?
This is not quite as clean as i would like, but this will work:
a = array([[1, 2, 3], ... [4, 5, 6], ... [7, 8, 9]]) m,n = a.shape b[:m-1,:n-1] = a[1:,1:] b array([[5, 6, 0], [8, 9, 0], [0, 0, 0]])
if b does not have to be the same shape as a, then it is really easy:
b = a[1:,1:]
