WitrynaCholesky 分解是把一个对称正定的矩阵表示成一个下三角矩阵L和其转置的乘积的分解。它要求矩阵的所有特征值必须大于零，故分解的下三角的对角元也是大于零的。Cholesky分解法又称平方根法，是当A为实对称正定矩阵时，LU三角分解法的变形。 Witryna19 mar 2024 · It is necessary to factorize a dense symmetric positive definite matrix of size n_1 (n_1 + n_2) in order to construct an interpolating (Hermite) normal spline.

In linear algebra, the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g., Monte Carlo simulations. It was … Zobacz więcej The Cholesky decomposition of a Hermitian positive-definite matrix A, is a decomposition of the form $${\displaystyle \mathbf {A} =\mathbf {LL} ^{*},}$$ where L is a Zobacz więcej The Cholesky decomposition is mainly used for the numerical solution of linear equations $${\displaystyle \mathbf {Ax} =\mathbf {b} }$$. If A is symmetric and positive definite, then we can solve $${\displaystyle \mathbf {Ax} =\mathbf {b} }$$ by … Zobacz więcej Proof by limiting argument The above algorithms show that every positive definite matrix $${\displaystyle \mathbf {A} }$$ has a Cholesky decomposition. This result can be extended to the positive semi-definite case by a limiting … Zobacz więcej A closely related variant of the classical Cholesky decomposition is the LDL decomposition, $${\displaystyle \mathbf {A} =\mathbf {LDL} ^{*},}$$ Zobacz więcej Here is the Cholesky decomposition of a symmetric real matrix: And here is its LDL decomposition: Zobacz więcej There are various methods for calculating the Cholesky decomposition. The computational complexity of commonly used algorithms is O(n ) in general. The algorithms … Zobacz więcej The Cholesky factorization can be generalized to (not necessarily finite) matrices with operator entries.
