planerot

Givens plane rotation

Syntax

• [G,y] = planerot(x)
  

Description

[G,y] = planerot(x) where x is a 2-component column vector, returns a 2-by-2 orthogonal matrix G so that y = G*x has y(2) = 0.

Examples

• x = [3 4];
  [G,y] = planerot(x')
  
  G  =
      0.6000    0.8000
     -0.8000    0.6000
  
  y =
       5
       0
