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 discovered by André-Louis Cholesky for real matrices, and posthumously published in 1924. When it is applicable, the Cholesky decomposition is roughly twice as efficient as the LU decomposition for … WebJun 16, 2024 · Definition 1: A matrix A has a Cholesky Decomposition if there is a lower triangular matrix L all whose diagonal elements are positive such that A = LL T.. …
