Vector’s Length
To calculate the
length of a
vector, all of the element of
the column
matrix that
represented a
vector
must be squared and added up. Afterward, the result of this
addition undergoes square root operation.
Example:
2
Vector A
4

Unit Vector/ Vector Normalization
Vector
normalization is
a
process
to
compute a
vector
with
length
of
one
(1),
which
is conducted by dividing each component of the vector
with the length of
a
vector.
Example:
2
Vector A
4
