The power method for lp norms
Webb3 aug. 2024 · The Python code for calculating L1 norm using Numpy is as follows : from numpy import array from numpy.linalg import norm arr = array([1, 2, 3, 4, 5]) print(arr) norm_l1 = norm(arr, 1) print(norm_l1) Output : [1 2 3 4 5] 15.0 Let’s try calculating it for the array with negative entries in our example above.
