MatrixRowReduce Method (Double, Point3d, Double) |
Row reduces a matrix as the first step in solving M*X=b where
b is a column of 3d points.
Namespace:
Rhino.Geometry
Assembly:
RhinoCommon (in RhinoCommon.dll)
Since: 5.0
Syntax public int RowReduce(
double zeroTolerance,
Point3d[] b,
out double pivot
)
Public Function RowReduce (
zeroTolerance As Double,
b As Point3d(),
<OutAttribute> ByRef pivot As Double
) As Integer
Parameters
- zeroTolerance
- Type: SystemDouble
(>=0.0) zero tolerance for pivot test. If the absolute value of a pivot
is <= zero_tolerance, then the pivot is assumed to be zero.
- b
- Type: Rhino.GeometryPoint3d
An array of RowCount 3d points that is row reduced with the matrix.
- pivot
- Type: SystemDouble
The value of the smallest pivot is returned here.
Return Value
Type:
Int32Rank 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.
