DoubleComplexQRLeastSqFactor(DoubleComplexMatrix, Double) 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
public void Factor(
	DoubleComplexMatrix A,
	double tolerance
)

Parameters

A  DoubleComplexMatrix
A matrix.
tolerance  Double
Tolerance for computing the numerical rank of the matrix A. If A = QR is the QR factorization of A, then elements on the main diagonal of R are considered to be zero if their absolute value is less than or equal to tolerance.
Remarks
For the QR least squares method to succeed, the matrix A must have full rank.
