Good Morning!
I want to get out the state space form of a thin plate with matlab interface... If I type:
sp1 = model.sol('sol1').feature.create('sp1','StateSpace');
sp1.set('A','on');
I´ll get the error message:
Messages:
Unknown property
- Property: A
I can just extract MA,MB,C,D but no MC,A,B matrix?
And why is MB always zero, altough there is an excitation?
Does anyone know hot to fix this problem?
Thanks!

There is following proplem with the documentation:
In the User´s Guide of Matlab Interface there were several choices to define mphstate: MA,MB,A,B,C,D,Mc,Null,ud,x0.
If on look in the local html help, there is a different description?!
You can find the local htmal help somewhere here:
file:///C:/COMSOL40a/doc/html/wwhelp
maybe a hint for some who are dealing with state-space
bye...
