Hi,
I'm interested in efficient implementations of various vector and matrix
norms.
Please can anyone give me some short examples regarding the following
norms
for
vectors :
1. Frobenius norm
2. L_1 norm is sum of absolute values
3. L_2 norm
4. L_\infty or maximum norm
5. p-norm
and matrices:
matrix spectral norm or matrix 2-norm
Frobenius norm ||A||_F
p-norms ||A||_p
Thanks in advance.
Nils
