Using the vecnorm() function in MATLAB is a convenient and efficient way to find the norm of each row of a matrix.Basic Syntax:output = vecnorm(matrix, normType, dimension); Parameters:matrix: The input data, which can be a vector, matrix, or N-dimensional array. normType: The type ...
d = norm(b-a) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. d = 2.8284 几何上,两点之间的距离: 2-Norm of Matrix clc clear close all % Calculate the 2-norm of a matrix, which is the largest singular value. X = [2 0 1;-1 1 0;-3 3 0]; n = norm(X) % n ...
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 ...
n = norm(A,‘fro‘) The Frobenius-norm of matrix A, sqrt(sum(diag(A‘*A))). 5/6 以此为例; A = 0 1 2 3 4 5 6 7 8 在MATLAB中分别输入如下指令: norm(A)/norm(A,2),返回的是矩阵A的二范数,(二范数j就是矩阵A的2范数就是 A的转置矩阵乘以A特征根 最大值的开根号) norm(A,1)...
