MUSIC Method for Spectrum Estimation
• music(E, N)—Implements the MUltiple SIgnal Classifier (MUSIC) method of spectral estimation.
The function returns a vector half as long as the original data plus 1.
Arguments
• E is a matrix containing eigenvectors of the signal autocorrelation matrix
• N is an integer number of eigenvectors to assign to the noise, not larger than the length of the original signal.
