planerot

Givens plane rotation.

Syntax

• [G, Y] = planerot(X)

Input argument

• X - two-element column vector.

Output argument

• G - 2 by 2 orthogonal matrix.

• Y - Y = G * X with Y(2) = 0.

Description

[G, Y] = planerot(X) computes the Givens rotation matrix for the two-element column vector X.

Example

X = [4; 5];
[G, X] = planerot(X)
