A Cholesky decomposition represents a matrix as the product of a lower-left triangular matrix and its transpose. For example:

The Choleksy decomposition of a symmetric, positive definite matrix can be obtained using the CholeskyDecomposition()()()() method of the SymmetricMatrix class.
Here is an example that uses a Cholesky decomposition to solve a linear algebra problem.
// Solve Ax = b via Cholesky decomposition CholeskyDecomposition CD = A.CholsekyDecomposition(); ColumnVector b = new ColumnVector(1.0, 2.0, 3.0); ColumnVector x CD.Solve(b);
