Vector and Matrix Norms

The p-norm of a vector x

is computed by norm(x,p). This is defined by any value of p > 1, but the most common values of p are 1, 2, and . The default value is p = 2, which corresponds to Euclidean length.

[norm(v,1) norm(v) norm(v,inf)]

ans =
      3.0000    2.2361    2.0000

The p-norm of a matrix A,

can be computed for p = 1, 2, and by norm(A,p). Again, the default value is p = 2.

[norm(C,1) norm(C) norm(C,inf)]

ans =
     19.0000   14.8015   13.0000
