Use a DLL in Simulink

Hi to all,

i've created a DLL in C# language and i want to use it in simulink.

I'm able to use in Matlab command line:

 dllPath = fullfile('c:','OwnProtocol2.dll');
 NET.addAssembly(dllPath);
 OwnProtocol2.sendsMeasures.writeInt()

How can i do this in Simulink?

The version of Matlab is 2010b

You can use a s-function to call the DLL. To do this you would need a header file describing the functions inside the DLL so the s-function knows how to call the functions inside the code. I'm not overly familiar with C# so I'm not sure how easy this will be but I am sure it is doable.

After you write the code just make sure to include the DLL in the mex line.

For example

mex mysfun.c myDLL.dll

Doesn't exist header file in C#...

Not sure if you can link .NET assemblies directly against C-MEX S-functions (or any generic DLLs for that matter), but if you know how to invoke .NET assemblies from generic C/C++ DLLs, you can follow the same technique for C S-functions. Alternately, it might be easier to continue using your MATLAB code to call into the assembly. You can call MATLAB code from Simulink using the Interpreted MATLAB Function block or MATLAB S-Functions.
