svplot
singular-value sigma-plot
Calling Sequence
[SVM]=svplot(sl,[w])
Arguments
- sl
syslin
list (continuous, discrete or sampled system)- w
real vector (optional parameter)
Description
computes for the system sl=(A,B,C,D)
the singular values of its transfer function matrix:
G(jw) = C(jw*I-A)B^-1+D or G(exp(jw)) = C(exp(jw)*I-A)B^-1+D or G(exp(jwT)) = C(exp(jw*T)*I-A)B^-1+D
evaluated over the frequency range specified by w
. (T is the sampling
period, T=sl('dt')
for sampled systems).
sl
is a syslin
list representing the system
[A,B,C,D]
in state-space form. sl
can be continuous or
discrete time or sampled system.
The i
-th column of the output matrix SVM
contains the singular
values of G
for the i
-th frequency value w(i)
.
SVM = svplot(sl)
is equivalent to
SVM = svplot(sl,logspace(-3,3)) (continuous)
SVM = svplot(sl,logspace(-3,%pi)) (discrete)
