MatrixRowReduce Method (Double, Double, Double)
Row reduces a matrix to calculate rank and determinant.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.50000.0 (5.0.20693.0)
Syntax
public int RowReduce(
	double zeroTolerance,
	out double determinant,
	out double pivot
)

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.
