What if one of the eigenvalues is zero?
Geometrically, having one or more eigenvalues of zero simply means the nullspace is nontrivial, so that the image is a "crushed" a bit, since it is of lower dimension.
Can all eigenvalues be zero?
Eigenvalues may be equal to zero. We do not consider the zero vector to be an eigenvector: since A 0 = 0 = λ 0 for every scalar λ , the associated eigenvalue would be undefined.
What is the music algorithm?
The basic idea of MUSIC algorithm is to conduct characteristic decomposition for the covariance matrix of any array output data, resulting in a signal subspace orthogonal with a noise subspace corresponding to the signal components.
What is root music algorithm?
The multiple signal classification (MUSIC) algorithm used by rootmusic is the same as that used by pmusic . The algorithm performs eigenspace analysis of the signal's correlation matrix in order to estimate the signal's frequency content.
