What is the Cholesky Decomposition Calculator & How does it work?
Cholesky decomposition is a method for decomposing a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose. This technique is widely used in numerical analysis to solve linear systems efficiently.
The Cholesky decomposition can be represented as: A = LLT, where A is the original matrix, L is the lower triangular matrix, and LT is the transpose of L. This method simplifies solving linear equations and computing matrix inverses.
