MatrixRowReduce Method (Double, Double, Double)

Row reduces a matrix to calculate rank and determinant.

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

Since: 5.0

Syntax

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

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

Parameters

zeroTolerance: Type: SystemDouble
(>=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: SystemDouble
value of determinant is returned here.
pivot: Type: SystemDouble
value of the smallest pivot is returned here.

Return Value

Type: Int32
Rank of the matrix.

Remarks

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