The task is to organize data exchange between the simulation program IPSEpro and Matlab. I'm trying that:
app = actxserver('PSE.Application');% Start IPSEpro
proj = invoke(app,'openProject','D:\example.pro'); %Call project file
run = invoke(proj, 'runSimulation' ,0); %Run simulation
object = invoke(proj,'findObject','generator001'); %Call the object
temp = invoke(object,'findItem',0,'power'); %Call the parameter of the object
P = invoke(temp,'value'); %Return the value of the parameter
The error:
Error using Interface.PSE_Application.openProject.findObject.findItem/set
Invoke Error: Unknown name or named argument
Error in example (line 9)
P = set(temp,'Value',8);
What can be the problem? Also, I can't get the list of COM object properties and interfaces, because the function get(app) returns an empty value.

The line shown in the error message does not match the code you've given.
In any case, without documentation of the COM interface there's little we can do to help you.

Without the documentation of the COM interface, there's not much we can do to help. I have seen cases where matlab does not want to show the COM interface with methodsview, properties, etc. In that case, you can use the OLE/COM viewer or the object browser in Visual Studio or in any Office program (under the hidden by default developer tab).
