Does anyone know how to determine the feature of special vectors that are the result of the Matlab function svd?
Let be:
B = U*S*V'
is an admissible decomposition {t20> of a real or complex matrix 2 into 2, then:
B = (U*c)*S *(V*c)'
where cis a matrix that changes the sign of one or both special vectors:
c = diag([1 -1]), diag([-1 1]) or diag([-1 -1]).
I want to know how the Matlab algorithm svddetermines the sign of singular vectors in U and V.
