"orthonormal" basis code example

Example 1: orthonormal basis

In mathematics, particularly linear algebra, an orthonormal basis 
for an inner product space V with finite dimension is a basis for 
V whose vectors are orthonormal, that is, they are all unit vectors
and orthogonal to each other.

Example 2: orthonormal basis

Orthogonal basis are called "Orthonormal"
if all vectors in the basis are unit vectors.
