Normalize

Normalize[v]
gives the normalized form of a vector v.

Normalize[z]
gives the normalized form of a complex number z.

normalizes with respect to the norm function f.

Normalize[v] is effectively v/Norm[v], except that zero vectors are returned unchanged.

Except in the case of zero vectors, Normalize[v] returns the unit vector in the direction of v.

For a complex number z, Normalize[z] returns z/Abs[z], except that Normalize gives .

Power method to find the eigenvector associated with the largest eigenvalue:

This is consistent (up to sign) with what Eigenvectors gives:

The eigenvalue can be found with Norm:
