Integrating Matlab Coder with c#

Hi,

I want to integrate Matlab Coder output with a C# project in Visual Studio. My main idea is:

• Create a *.m script in Matlab
• Make sure the script is compatible with Matlab Coder.
• Generate a C++ shared library (DLL) with Matlab Coder
• Integrate with C# using something like this:

 //Starts the model execution. May take several minutes
  public static class DllHelper
    {
        [DllImport(@"test.dll",CallingConvention=CallingConvention.Cdecl,EntryPoint = "Run()")]
        public static extern int Run();
    }

• Also, I would like to be able to stop the execution and retrieve some partial results. To do this, I was thinking in two methods: StopExecution and RetrievePartialResults

[DllImport(@"test.dll",CallingConvention=CallingConvention.Cdecl,EntryPoint = "StopExecution ()")]
public static extern int StopExecution ();

[DllImport(@"test.dll",CallingConvention=CallingConvention.Cdecl,EntryPoint = "RetrievePartialResults()")]
public static extern MyResults RetrievePartialResults();

1. Is it possible to do?
2. If no, is there any alternatives?
3. If yes, where can I find more examples?

In addition to Bill's answer, generating the interface binding the generated C code to C# with something like SWIG is also an option. Here's an example:

As for starting and stopping the application, there isn't a built-in way for Coder to make a program interruptible. You'll need to design your MATLAB code to support such a behavior by possibly adding StopExecution and RetrievePartialResults entry-point functions which do the right thing when run in your deployed environment.

Yes, it's possible to use MATLAB Coder to integrate with C# applications. One would need to make some manually changes at the interface. Please see this article for more details:
