BlasLevel1..::..Drotg Method

BlasLevel1 Class See Also 
Generates the elements for a Givens plane rotation.

Namespace: Extreme.Mathematics.LinearAlgebra.Providers
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 4.2.11333.0 (4.2.12253.0)

Syntax

C# 
                      public abstract void Drotg(
	ref double a,
	ref double b,
	ref double c,
	ref double s
)
Visual Basic (Declaration) 
                      Public MustOverride Sub Drotg ( _
	ByRef a As Double, _
	ByRef b As Double, _
	ByRef c As Double, _
	ByRef s As Double _
)
Visual C++ 
                      public:
virtual void Drotg(
	double% a, 
	double% b, 
	double% c, 
	double% s
) abstract
F# 
                      abstract Drotg : 
        a:float byref * 
        b:float byref * 
        c:float byref * 
        s:float byref -> unit

Parameters

a
Type: System..::..Double%
The first element of the input vector. On exit, this value is overwritten with the rotated element r.
b
Type: System..::..Double%
The second element of the input vector. On exit, this value is overwritten with the reconstruction value z.
c
Type: System..::..Double%
On exit, this value is overwritten with the first rotation element, the cosine of the rotation angle.
s
Type: System..::..Double%
On exit, this value is overwritten with the second rotation element, the sine of the rotation angle.
