Remarks

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.

Example

Here is an example that uses a Cholesky decomposition to solve a linear algebra problem.

C#
// 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);

Properties

Dimension Gets the dimension of the system.
