Method Math.Matrix()->normv()

Method normv

float norm()
float norm2()
Matrix normv()

Description

Norm of the matrix, and the square of the norm of the matrix. (The later method is because you may skip a square root sometimes.)

This equals |A| or sqrt( A₀² + A₁² + ... + A_n² ).

It is only usable with 1xn or nx1 matrices.

m->normv() is equal to m*(1.0/m->norm()), with the exception that the zero vector will still be the zero vector (no error).
