Row reduces a matrix to calculate rank and determinant.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0

C#

public int RowReduce(
	double zeroTolerance,
	out double determinant,
	out double pivot
)

VB

Public Function RowReduce ( 
	zeroTolerance As Double,
	<OutAttribute> ByRef determinant As Double,
	<OutAttribute> ByRef pivot As Double
) As Integer

zeroTolerance

Type: System.Double
(>=0.0) zero tolerance for pivot test. If a the absolute value of a pivot is <= zeroTolerance, then the pivot is assumed to be zero.

determinant

Type: System.Double
value of determinant is returned here.

pivot

Type: System.Double
value of the smallest pivot is returned here.

Type: Int32
Rank of the matrix.

The matrix itself is row reduced so that the result is an upper triangular matrix with 1's on the diagonal.
