# Normalize

 Normalize[v] gives the normalized form of a vector v. Normalize[z]gives the normalized form of a complex number z. Normalizenormalizes 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.
• Normalize is effectively , except when there are zeros in .

is a symmetric matrix with distinct eigenvalues:
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:
