Hi all, What is the fastest and lowest memory consumption way to compute this? y = np.arange(2**24) bases = y[1:] + y[:-1] Actually it is already quite fast, but i'm not sure whether it is occupying some temporary memory is the summation. Any help is appreciated.
Is it OK to modify y? If so:
y = np.arange(2**24) z = y[1:] + y[:-1] # <--- Slow way y[:-1] += y[1:] # <--- Fast way (y[:-1] == z).all() True
