Feb 07, 2012 · The function you're after is numpy.linalg.norm. (I reckon it should be in base numpy as a property of an array -- say x.norm()-- but oh well). import numpy as np x = np.array([1,2,3,4,5]) np.linalg.norm(x) You can also feed in an optional ord for the nth order norm you want. Say you wanted the 1-norm: np.linalg.norm(x,ord=1) And so on.
