Scilab Function

givens - Givens transformation

Calling Sequence

U=givens(xy)
U=givens(x,y)
[U,c]=givens(xy)
[U,c]=givens(x,y)

Parameters

Description

U = givens(x, y) or U = givens(xy) with xy = [x;y] returns a 2 x 2 unitary matrix U such that:

U*xy=[r;0]=c .

Note that givens(x,y) and givens([x;y]) are equivalent.

Examples


A=[3,4;5,6];
U=givens(A(:,1));
U*A
