	Decompose	Calculates the actual QR decomposition. (Overrides Decomposition..::..Decompose()()()().)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	EstimateConditionNumber	Calculates an estimate for the condition number of the matrix. (Overrides LinearOperator..::..EstimateConditionNumber()()()().)
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetDeterminant	Calculates the determinant of the decomposed matrix. (Overrides LinearOperator..::..GetDeterminant()()()().)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)

	GetObjectData	Populates a SerializationInfo with the data needed to serialize the target object. (Inherited from LinearOperator.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsSingular	Gets a value indicating whether the BaseMatrix of this decomposition is singular. (Inherited from Decomposition.)
	LeastSquaresSolve	Overloaded.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Multiply	Overloaded.
	MultiplyTranspose	Overloaded.
	Rank	Overloaded. Returns the numerical rank of the matrix.
	SetSingular	Sets a flag that indicates the underlying matrix of this decomposition is singular. (Inherited from Decomposition.)
	Solve	Overloaded. Solves the system of simultaneous linear equations represented by this instance. Solves the system of simultaneous linear equations represented by this instance.
	SolveTo	Solves the system for the specified right-hand side. (Inherited from LinearOperator.)
	SolveTranspose	Overloaded. Solves the transposed system of simultaneous linear equations represented by this instance.
	SolveTransposeTo	Solves the transposed system for the specified right-hand side. (Inherited from LinearOperator.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Properties

	Name	Description
	BaseMatrix	Gets the underlying matrix of the decomposition. (Inherited from Decomposition.)
	ColumnCount	Gets the number of columns in the matrix. (Inherited from Decomposition.)
	ColumnPermutation	Returns the permutation used to permute the columns of the matrix.
	Done	Gets or sets a value that indicates whether the decomposition has been performed. (Inherited from Decomposition.)
	Factors	Gets a collection of the matrix factors that make up the decomposition. (Overrides Decomposition..::..Factors.)
	OrthogonalFactor	Gets the orthogonal matrix Q of this QRDecomposition.
	Overwrite	Gets or sets a value indicating whether the BaseMatrix should be overwritten by its decomposition. (Inherited from Decomposition.)
	RowCount	Gets the number of rows in the matrix. (Inherited from Decomposition.)
	TrimmedUpperTriangularFactor	Gets the upper triangular matrix R of this QRDecomposition.
