Function: rms
RMS RMS value of signal
  Usage: y = rms(f);
         y = rms(f,...);

  RMS(f) computes the RMS (Root Mean Square) value of a finite sampled
  signal sampled at a uniform sampling rate. This is a vector norm
  equal to the l^2 averaged by the length of the signal.

  If the input is a matrix or ND-array, the RMS is computed along the
  first (non-singleton) dimension, and a vector of values is returned.

  The RMS value of a signal x of length N is computed by

                           N
     rms(f) = 1/sqrt(N) ( sum |f(n)|^2 )^(1/2)
                          n=1

  RMS takes the following flags at the end of the line of input
  parameters:

    'ac'       Consider only the AC component of the signal (i.e. the mean is
               removed).

    'dim',d    Work along specified dimension. The default value of []
               means to work along the first non-singleton one.
