is named vector. The entries 
may be real or complex. 
is the dimension of the vector.
The vector with all entries equal to 0 is also denoted by the symbol 0.
Given a scalar 
, the product 
is the vector with entries 
.
If 
are vectors of the same dimension, for any set of scalar coefficients 
, the vector 
is a linear combination of 
. Vectors are said to be linearly independent if only if . Otherwise, they are said to be linearly ...
