CreateGivensRotation(Single, Single, Single, Single)

Construct givens plane rotation.

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

Parameters

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