The DecompositionT class represents a decomposition of a matrix into a product of matrices with specific properties.

The DecompositionT class defines methods and properties that are shared by all decomposition classes. This includes methods related to solving systems of simultaneous linear equations defined by the LinearOperatorT abstract base class.

The DecompositionT class is an abstract base class and cannot be instantiated directly. Instead, use one of its derived classes. These are:

Notes to inheritors: When you inherit from DecompositionT, you must override the following members: EstimateConditionNumber, GetDeterminant, GetInverse, Rank(T), Solve(VectorT).
