MATLAB: Protecting a subsystem in simulink

simulink.modelreference.protect

I am trying to protect a subsystem block from third party but they should be able to run the simulation without identifying the model. I tried this by referencing the model and then coding but again it is giving error.

Is there anyone can help me with step by step procedure to protect the model?

You can find the documented API here:

https://de.mathworks.com/help/rtw/model-protection.html?s_tid=CRUX_lftnav

It is possible to authenticate for Viewing, Simulation, Code Generation and Modification.

Or check the doc in your installation by using the following commands:

>> doc Simulink.ModelReference.ProtectedModel.setPasswordForCodeGeneration%Add or provide encryption password for code generation from protected model
>> doc Simulink.ModelReference.ProtectedModel.setPasswordForModify%Add or provide password for modifying protected model
>> doc Simulink.ModelReference.ProtectedModel.setPasswordForSimulation%Add or provide encryption password for simulation of protected model
>> doc Simulink.ModelReference.ProtectedModel.setPasswordForView%Add or provide encryption password for read-only view of protected model

MATLAB: Protected External Methods

http://www.mathworks.com/help/techdoc/matlab_oop/brqy3km-14.html#brqy3km-15 under "Specify Method Attributes in classdef File" ...

Basically, inside the class definition create a methods block with properties Acess = protected. Inside that block add the function footprint.

methods (Access = protected)
  [a,b,c]=protectedmethod(x,y,z);
end

Then create a seperate m file in the root class directory named protectedmethod with the header

function [d,e,f]=protectedmethod(u,v,w)
