Thread Subject: Create state-space model

Noticed that the command "ss" has a different function in "System Identification Toolbox" than it does in "Control System Toolbox".

I don't have "Control System Toolbox" not installed anymore.
What other way ist there of creating a state-space model from A,B,C,D matrizes (manual)?

I hope there is one. If not, I have to admit, I'm a bit upset that such a basic command is not included in the ident-Toolbox. It's annoying to be able to create an SS system from data, but not by hand.

Thanks in advance for any help.

Hi Jonas, Sorry, I'm not 100% sure from your post, but are you saying you have the System iIentification Toolbox? If so is

>>doc idss

not suitable?
