  2. Eigenvalues and eigenvectors - Wikipedia

    en.wikipedia.org/wiki/Eigenvalues_and_eigenvectors

    For the real eigenvalue λ 1 = 1, any vector with three equal nonzero entries is an eigenvector. ... In the example, the eigenvalues correspond to the eigenvectors, ...

  3. Eigendecomposition of a matrix - Wikipedia

    en.wikipedia.org/wiki/Eigendecomposition_of_a_matrix

    A conjugate eigenvector or coneigenvector is a vector sent after transformation to a scalar multiple of its conjugate, where the scalar is called the conjugate eigenvalue or coneigenvalue of the linear transformation. The coneigenvectors and coneigenvalues represent essentially the same information and meaning as the regular eigenvectors and ...

  4. Eigenvalue algorithm - Wikipedia

    en.wikipedia.org/wiki/Eigenvalue_algorithm

    Given an n × n square matrix A of real or complex numbers, an eigenvalue λ and its associated generalized eigenvector v are a pair obeying the relation [1] =,where v is a nonzero n × 1 column vector, I is the n × n identity matrix, k is a positive integer, and both λ and v are allowed to be complex even when A is real.l When k = 1, the vector is called simply an eigenvector, and the pair ...

  5. Generalized eigenvector - Wikipedia

    en.wikipedia.org/wiki/Generalized_eigenvector

    In linear algebra, a generalized eigenvector of an matrix is a vector which satisfies certain criteria which are more relaxed than those for an (ordinary) eigenvector. [ 1 ] Let V {\displaystyle V} be an n {\displaystyle n} -dimensional vector space and let A {\displaystyle A} be the matrix representation of a linear map from V {\displaystyle V ...

  6. Eigenfunction - Wikipedia

    en.wikipedia.org/wiki/Eigenfunction

    Each value of λ corresponds to one or more eigenfunctions. If multiple linearly independent eigenfunctions have the same eigenvalue, the eigenvalue is said to be degenerate and the maximum number of linearly independent eigenfunctions associated with the same eigenvalue is the eigenvalue's degree of degeneracy or geometric multiplicity. [4] [5]

  7. Power iteration - Wikipedia

    en.wikipedia.org/wiki/Power_iteration

    In mathematics, power iteration (also known as the power method) is an eigenvalue algorithm: given a diagonalizable matrix, the algorithm will produce a number , which is the greatest (in absolute value) eigenvalue of , and a nonzero vector , which is a corresponding eigenvector of , that is, =.

  8. Singular value decomposition - Wikipedia

    en.wikipedia.org/wiki/Singular_value_decomposition

    ⁠ The vector ⁠ ⁠ can be characterized as a right-singular vector corresponding to a singular value of ⁠ ⁠ that is zero. This observation means that if ⁠ A {\displaystyle \mathbf {A} } ⁠ is a square matrix and has no vanishing singular value, the equation has no non-zero ⁠ x {\displaystyle \mathbf {x} } ⁠ as a solution.

  9. Jacobi eigenvalue algorithm - Wikipedia

    en.wikipedia.org/wiki/Jacobi_eigenvalue_algorithm

    Let be the vector space spanned by the eigenvectors of which correspond to a negative eigenvalue and analogously for the positive eigenvalues. If a ∈ W s {\displaystyle a\in W^{s}} then lim t → ∞ x ( t ) = 0 {\displaystyle {\mbox{lim}}_{t\rightarrow \infty }x(t)=0} ; that is, the equilibrium point 0 is attractive to x ( t ) {\displaystyle ...
