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.
