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.-function Px = music(x,p,M)
