Subspace Methods

Frequency and pseudospectrum estimates, multiple signal classification (MUSIC), root MUSIC

Obtain high-resolution frequency estimates using the multiple signal classification (MUSIC) algorithm and other subspace-based methods.

Functions

`peig`	Pseudospectrum using eigenvector method
`pmusic`	Pseudospectrum using MUSIC algorithm
`rooteig`	Frequency and power content using eigenvector method
`rootmusic`	Root MUSIC algorithm

The pmusic and peig functions provide two related spectral analysis methods:

Resolve closely spaced sinusoids using the MUSIC algorithm.

Replace calls to subspace pseudospectrum objects with function calls.
