hankelsv
Hankel singular values
Calling Sequence
[nk2,W]=hankelsv(sl [,tol]) [nk2]=hankelsv(sl [,tol])
Arguments
- sl
syslin
list representing the linear system (state-space).- tol
tolerance parameter for detecting imaginary axis modes (default value is
1000*%eps
).
Description
returns nk2
, the squared Hankel singular values of sl
and W = P*Q
= controllability gramian times observability
gramian.
nk2
is the vector of eigenvalues of W
.
