How to Calculate L2 Norm of a Vector? The notation for the L2 norm of a vector x is ‖x‖2. To calculate the L2 norm of a vector, take the square root of the sum of the squared vector values. Another name for L2 norm of a vector isEuclidean distance.This is often used for calc...

Common Vector Norms: L1, L2, and L∞ Norms In general, the Lp norm (or p-norm) of an n-dimensional vectorx= (x1,x2,x3,...,xn) for p >= 0 is given by: Let’s take a look at the common vector norms, namely, the L1, L2 and L∞ norms. ...
python import numpy as np from scipy.linalg import norm # 创建一个向量 vec = np.array([1, 2, 3]) # 计算向量的2-范数 norm_vec = norm(vec) print(f"The 2-norm of the vector is: {norm_vec}") 查看官方文档: 如果你不确定某个函数或属性的位置,建议查看scipy的官方文档。文档提供了关于...
