====RMS - rms measurement====

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

<code>RMS <var>A</var></code>

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

{|
|-
|A
|number or vector
|}

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

{|
|-
|<var>Y</var>
|root mean square (rms) of A (number)
|}

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

Compute root mean square of input <var>A</var>.

if <var>A</var> is a number:

<var>Y</var> = |<var>A</var>|

if <var>A</var> is a vector:

<var>Y</var> = ((<var>A</var>[0] + ... + <var>A</var>[n-1]) / n)1/2
n = number of elements of <var>A</var>
