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.
