Hi All,

is there a function which returns a list of all parameters needed by a simulink block diagramm? Of course no fix values (e.g. in a costant block), but all the names of variables which have to be in base work space to run the model.

Thank you very much.

Take a look at Simulink.findVars

Thanks, but unfortunately I'm restricted to Matlab 7.1 in the current project. As far as I know is this a new feature available in release 2010a

Have you tried
modelParams = get_param(modelName,'ReferencedWSVars');

This should give you a list of workspace parameters that are actually getting used in the model.

thank you checker i,

Yes, I have tried this. But I have the problem that this function only works if the parameters are already in the workspace. If they are not, I get an error message. In general this is exactly what I'm looking for, but I need this function before the parameters are loaded to workspace, because i have to manipulate them before.
