Eigenvector -- from Wolfram MathWorld

WebThis paper concerns a harmonic projection method for computing an approximation to an eigenpair (λ,x) of a large matrix A. Given a target point r and a subspace W that contains an approximation to x, the harmonic projection method returns an approximation (μ + ρ, x) to (λ, x). Three convergence results are established as the deviation e of x from W approaches … WebEigenvalues and eigenvectors are only for square matrices. Eigenvectors are by definition nonzero. Eigenvalues may be equal to zero. We do not consider the zero vector to be an eigenvector: since A0=0=λ0for everyscalar λ,the associated eigenvalue would be undefined.

V: Usual Rayleigh quotient for non-Hermitian matrices and linear elementary divisors Overview Citations (33) Related Papers (5) WebA has one eigenvalue λ of algebraic and geometric multiplicity 2. To say that the geometric multiplicity is 2 means that Nul ( A − λ I 2 )= R 2 , i.e., that every vector in R 2 is in the null space of A − λ I 2 . This implies that A − λ I 2 is the zero matrix, so that A is the diagonal matrix λ I 2 . In particular, A is diagonalizable. For example:
