  2. Toeplitz matrix - Wikipedia

    en.wikipedia.org/wiki/Toeplitz_matrix

    An Toeplitz matrix may be defined as a matrix where , =, for constants , …,. The set of n × n {\displaystyle n\times n} Toeplitz matrices is a subspace of the vector space of n × n {\displaystyle n\times n} matrices (under matrix addition and scalar multiplication).

  3. Levinson recursion - Wikipedia

    en.wikipedia.org/wiki/Levinson_recursion

    Levinson recursion or Levinson–Durbin recursion is a procedure in linear algebra to recursively calculate the solution to an equation involving a Toeplitz matrix.The algorithm runs in Θ(n 2) time, which is a strong improvement over Gauss–Jordan elimination, which runs in Θ(n 3).

  4. Circulant matrix - Wikipedia

    en.wikipedia.org/wiki/Circulant_matrix

    In linear algebra, a circulant matrix is a square matrix in which all rows are composed of the same elements and each row is rotated one element to the right relative to the preceding row. It is a particular kind of Toeplitz matrix .

  5. Woodbury matrix identity - Wikipedia

    en.wikipedia.org/wiki/Woodbury_matrix_identity

    This is applied, e.g., in the Kalman filter and recursive least squares methods, to replace the parametric solution, requiring inversion of a state vector sized matrix, with a condition equations based solution. In case of the Kalman filter this matrix has the dimensions of the vector of observations, i.e., as small as 1 in case only one new ...

  6. Block matrix - Wikipedia

    en.wikipedia.org/wiki/Block_matrix

    In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. [1] [2]Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller matrices.

  7. Sample matrix inversion - Wikipedia

    en.wikipedia.org/wiki/Sample_matrix_inversion

    Sample matrix inversion (or direct matrix inversion) is an algorithm that estimates weights of an array (adaptive filter) ... "Adaptive antenna systems" (PDF).

  8. Toeplitz Hash Algorithm - Wikipedia

    en.wikipedia.org/wiki/Toeplitz_Hash_Algorithm

    The Toeplitz Hash Algorithm describes hash functions that compute hash values through matrix multiplication of the key with a suitable Toeplitz matrix. [1] The Toeplitz Hash Algorithm is used in many network interface controllers for receive side scaling. [2] [3] As an example, with the Toeplitz matrix the key results in a hash as follows:

  9. Silverman–Toeplitz theorem - Wikipedia

    en.wikipedia.org/wiki/Silverman–Toeplitz_theorem

    In mathematics, the Silverman–Toeplitz theorem, first proved by Otto Toeplitz, is a result in series summability theory characterizing matrix summability methods that are regular. A regular matrix summability method is a linear sequence transformation that preserves the limits of convergent sequences . [ 1 ]
