music

  function Px = music(x,p,M) MUSIC Frequency estimation using the MUSIC algorithm. ----- USAGE Px=music(x,p,M) The input sequence x is assumed to consist of p complex exponentials in white noise. The frequencies of the complex exponentials and the variance of the white noise are estimated using the MUSIC algorithm. x : input sequence p : number of complex exponentials to find M : number of noise eigenvectors to use The frequency estimates are found from the peaks of the pseudospectrum Px.
