Quantlet: givenrot
Description: Decomposes an orthonormal matrix into a set of rotations by Givens rotation

Link:
Usage: out = givenrot (in)
Input:
in p x p matrix Outout
al p x (p-1)/2 vector

Example:

; loads the library pp

library ("pp")

; generate some vectors

x = normal(6,4)

; orthonormalize x 

o = orthonormal(x)

; check it

o'*o

Result:

gives the appropriate (4x4) identity matrix
