householder
Householder orthogonal reflexion matrix
Calling Sequence
u=householder(v [,w])
Arguments
- v
real or complex column vector
- w
real or complex column vector with same size as
v. Default value iseye(v)- u
real or complex column vector
Description
given 2 column vectors v, w of same size, householder(v,w) returns a unitary
column vector u, such that (eye()-2*u*u')*v is proportional to w.
(eye()-2*u*u') is the orthogonal Householder reflexion matrix .
w default value is eye(v). In this case vector (eye()-2*u*u')*v is the
vector eye(v)*norm(v).
