Length Norm

Scaling Normalization

The length (or norm) of vector [4 3]' is therefore V42 + 32 (norm) of vector [3 4]'. The norm of vector b is noted ||b||.

5 ; it is also the length

The comparison of different vectors, as to their directions, often requires an operation called scaling. In the scaled vector, all elements are divided by the same characteristic value. A special type of scaling is called normalization. In the normalized vector, each element is divided by the length of the vector:
