Problems with linear algebra
Hello,
I have the following problem. Let U be an unitary matrix (i.e., assume that it is a rotation in some Hilbert space H), and I want to decompose U as a product of two reflections through two subspaces A,B in H, i.e.,
where
is a projection onto subspace X, and I is the identity.
what are the basis vectors for subspaces A and B?
