Hi, when I calculate the norm of vector a3, I get different values in julia vs MatLab [julia] [matlab]

Actually, the previous posts have it backwards, as far as the names of the norms are concerned. For matrices, it’s opnorm that gives you the induced matrix 2-norm, \|A\|_2 = \sup_{x\neq0} \|Ax\|_2/\|x\|_2 = max singular value, whereas norm gives the root-sum-squares Frobenius norm, \|A\|_F = \sqrt{\…

JULIA matrix norm is different MATLAB

wait , no

n = norm( X ) returns the 2-norm or maximum singular value of matrix X , which is approximately max(svd(X)) .
