The task is to create 361x721x11 copies of ll as fast as possible preferably using the functions in numpy. The following code works ll = ones((13,25)) # used ones() for illustration purposes. My real array isn't actually just a bunch of ones ll_ijk = np.repeat(np.repeat(np.repeat(ll[...,None,None,None],361,axis = 2),721,axis = 3),11,axis = 4) where I used nested calls of the repeat function for each new dimension, but it took about 4-5 seconds to complete. Is there a more/most efficient way of doing this? Continue reading...
