Vector and matrix norms Syntax n = norm(v) n = norm(v,p) n = norm(X) n = norm(X,p) n = norm(X,'fro') Description n = norm(v)返回向量v的欧几里德范数。该范数也称为2范数,向量幅度或欧几里德...
n = norm(A,2) The largest singular value (same as norm(A)). n = norm(A,inf) The infinity norm, or largest row sum of A, max(sum(abs(A'))) n = norm(A,'fro') The Frobenius-norm of matrix A, sqrt(sum(diag(A'*A))). norm Vector and matrix norms Syntax Description Theno...
norm(A,p) Returns sum(abs(A).^p)^(1/p), for any 1 <= p <= ∞. norm(A) Returns norm(A,2) norm(A,inf) Returns max(abs(A)). norm(A,-inf) Returns min(abs(A)). 当A是矩阵时 n = norm(A) returns the largest singular value of A, max(svd(A)) n = norm(A,1) The ...
output = vecnorm(matrix, normType, dimension); Parameters:matrix: The input data, which can be a vector, matrix, or N-dimensional array. normType: The type of norm to be computed, such as 2 for the Euclidean norm or inf for the infinity norm. dimension (optional): Specifies whether ...
