sva
singular value approximation
Calling Sequence
[U,s,V]=sva(A,k) [U,s,V]=sva(A,tol)
Arguments
- A
real or complex matrix
- k
integer
- tol
nonnegative real number
Description
Singular value approximation.
[U,S,V]=sva(A,k)
with k
an integer
>=1, returns U,S
and V
such that
B=U*S*V'
is the best L2 approximation of
A
with rank(B
)=k
.
[U,S,V]=sva(A,tol)
with tol
a real
number, returns U,S
and V
such that
B=U*S*V'
such that L2-norm of A-B
is at most tol
.
