The autocorrelation function (ACF) for a time seriesyt,t= 1,...,N, is the sequenceρh,h= 1, 2,...,N– 1. The partial autocorrelation function (PACF) is the sequenceϕh,h,h= 1, 2,...,N– 1. The theoretical ACF and PACF for the AR, MA, and ARMA conditional mean models...
i want to find the sum of the below.but i am getting an error.please help me. i write the program in two ways.both are same.but both getting different answer for i=1:20 s(i)=(2*(acf(i+1)^2)); s1=sum(s(i)); end

This paper describes a MATLAB program with a graphical user interface (GUI), for a signal processing based on the Auditory Image Model [S. Bleeck et al., Acta Acustica united with Acustica, 90 (2004) 781-787], followed by the summary autocorrelation function (SACF) and the summary ...
I have a sound wave representing a piano piece played at a steady tempo, and would like to get a graph of the saliency of each beat. I understand that this is done by plotting the autocorrelation function, however I don't quite understand why a graph of r coefficients against ...

An apparatus for analyzing an audio signal with regard to rhythm information of the audio signal by using an autocorrelation function comprises a filter bank for separating the audio signal into at least two sub-band signals. The sub-band signals are examined with regard to periodicities by an ...
it looks like you might be able to build it by using the vector and the TOEPLITZ function (or cousins).Using
I'd appreciate a more in-depth answer. I have thought about this issue, have done some limited testing, and one of our PhD's has investigated the narxnet code more closely. Preliminary evidence is pointing to my above assertion that Matlab does not perform separate narxnet calculations...
