Is it possible to pass variables form Matlab app workspace (a struct in matlab app made like this app.Workspace.Subworkspace.Variable), directly to Simulink, without using Matlab Workspace or an external file?

Yes, you can pass variables from a MATLAB app workspace directly to Simulink without using the MATLAB workspace or an external file. You can achieve this by using the Simulink.SimulationInput object to set parameters directly from your app's workspace.

As I found a few technical articles around detail problems around compiling lookup tables, I conclude this is generally possible. But I am ot an expert for this. I am happy to connect you with MathWorks staff to help you further. Can you send me a personal message for further conversation if you are interested?

@Andreas Goser Thank you, I managed to pass the variables and vectors form matlab app workspace to simulink.
% Create a SimulationInput object for your model
simIn = Simulink.SimulationInput('Your_Simulink_Model');
simIn = simIn.setVariable('Variable_name_in_Simulink', app.Workspace.Subworkspace.Variable);
If I will need further assistance I will send you a personal message!
