Method Math.Matrix()->norm2()

Method norm
Method norm2
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).
