DoubleQRLeastSqFactor(DoubleMatrix, Boolean) Method

Factors a given matrix so that it may be used to solve least squares problems. The specified tolerance is used in computing the numerical rank of the matrix.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

C++

Copy

public void Factor(
	DoubleMatrix A,
	bool inPlace
)

Public Sub Factor ( 
	A As DoubleMatrix,
	inPlace As Boolean
)

public:
void Factor(
	DoubleMatrix^ A, 
	bool inPlace
)

member Factor : 
        A : DoubleMatrix * 
        inPlace : bool -> unit

Parameters

A DoubleMatrix: A matrix.
inPlace Boolean: If true, the QR decomposition performed during the least square computation will overwrite the input matrix A. If false the input matrix A will be preserved at the expense of making a copy of A. Note that if inPlace is true, the input matrix A will not be checked for valid input (NaN's and infinity's).

Remarks

For the QR least squares method to succeed, the matrix A must have full rank.
