Using C# functions and forms in Matlab

This script shows how C# functions/classes can be used in Matlab

Description

This script shows how C# functions/classes and forms (gui) can be used in Matlab.

The zip contains:
- a example c# class (ComMatlab.cs) with different inputs and outputs functions.
- a info_ComMatlab.txt with the commands how to compile and register a c# activex control
- a ComMatlabtest.m for testing the c# functions.

- a example c# class (MatlabGUI.cs) which creates a form for user input (uses the other MatlabGUI cs files)
- a info_MatlabGUI.txt with the commands how to compile and register a c# activex control from multiple .cs files
- a MatlabGUItest.m for testing the c# userinput Form

(The MatlabGUI Form is designed with Visual Studio 2005)

Dear Dirk-Jan Kroon,
Thanks for your post. Compiling is ok but when I try to use in Matlab, i got following error :
>> net = actxserver('MatlabGUI.FormControlClass');
??? Error using ==> feval
Server Creation Failed: Le fichier spécifié est introuvable.
If you could help, would be nice. Thanks

Dear Dirk-Jan Kroon,
I found my pb, the code works fine now. The pb was that I did not subscribe to COM Interop in the project properties.
Thanks again for this very useful post.

I tried to configure MSVC to compile the dll (used File->New->Project->CisualC#->Class Library) and got the error

>> ComMatlabtest
??? Error using ==> actxserver at 91
Server creation failed. Invalid ProgID 'ComMatlab.ComMatlabClass'

Error in ==> ComMatlabtest at 7
net = actxserver('ComMatlab.ComMatlabClass'); % Load the ActiveX ComMatlab

I traced it down to a project properties setting under "Application" where you must select the "Assembly Information" button and then select the "Make assembly COM-Visible" checkbox.
