====DOT - dot product====

=====Usage:=====

<code>DOT <var>A</var> <var>B</var></code>

=====Inputs:=====

{|
|-
|A
|number or vector
|-
|B
|same type as A
|}

=====Outputs:=====

{|
|-
|Y
|dot product A.<var>B</var> (number)
|}

=====Function:=====

Compute the dot product of <var>A</var> and <var>B</var>.

{|
|-
|if A and <var>B</var> are numbers:
|Y = <var>A</var>.<var>B</var>
|-
|if A and <var>B</var> are vectors:
|Y = <var>A</var>[0].<var>B</var>[0] + ... + <var>A</var>[n-1].<var>B</var>[n-1];
|-
|
|n = number of elements of A|<var>B</var>
