Dear all,
if I have two ndarray arr1 and arr2 (with the same shape), is there some
difference when I do:
arr = arr1 + arr2
and
arr = np.add(arr1, arr2),
and then if I have more than 2 arrays: arr1, arr2, arr3, arr4, arr5, then I
cannot use np.add anymore as it only recieves 2 arguments.
then what's the best practice to add these arrays? should I do
arr = arr1 + arr2 + arr3 + arr4 + arr5
or I do
arr = np.sum(np.array([arr1, arr2, arr3, arr4, arr5]), axis=0)?
because I just noticed recently that there are functions like np.add,
np.divide, np.substract... before I am using all like directly arr1/arr2,
rather than np.divide(arr1,arr2).
best regards,
Chao
