Matrix Decompositions

A matrix decomposition or factorization is a representation of a matrix as a product of two or more matrices. Decomposing a matrix is often the first step in the solution of a problem in linear algebra. The matrices in the decomposition usually have some special properties, which can be used to simplify the solution. A decomposition is often called a factorization. The two words are synonyms.

The Extreme Optimization Mathematics Library for .NET contains a series of classes that implement a number of standard decompositions. These classes are contained in the Extreme.Mathematics.LinearAlgebra namespace.

In this section:

The LU Decomposition
The QR Decomposition
The Singular Value Decomposition
The Cholesky Decomposition
The Symmetric Eigenvalue Decomposition
Decompositions of Band Matrices
Solving Linear Systems and Related Operations
