2025.2 English

This function computes the Cholesky decomposition of matrix \(A\).

\[A = L {L}^*\]

where \(A\) is a Hermitian positive-definite matrix of size \(n \times n\), \(L\) is a lower triangular matrix with real and positive diagonal entries, and \({L}^*\) denotes the conjugate transpose of the matrix \(L\). Every Hermitian positive-definite matrix (and thus also every real-valued symmetric positive-definite matrix) has a unique Cholesky decomposition.

The Cholesky library element has configurable data types and matrix sizes, a configurable number of frames, and support for parallelism.
