CreateGivensRotation(Double, Double, Double, Double)

Construct givens plane rotation.

C# 
public override void CreateGivensRotation(
	ref double a,
	ref double b,
	out double c,
	out double s
)

Parameters

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