Simulink and COM (Component Object Model)

Hello all,

I know that MATLAB can utilize COM and acts as server or client. What I want to know is, whether a direct interface between Simulink and COM possible is. If not, maybe it can communicate with COM via MATLAB interface.

Any idea?

Thanks!

Simulink has to be run in Matlab. Everything you do in Simulink can be done with a command in Matlab. So, I think there is no direct interface between Simulink and COM. It has to be done through Matlab.

To interface MATLAB and COM, I use a MATLAB function. Is it possible to integrate the function in Simulink using S-Function?

My target is to have Simulink outputs the data in real time to COM

Fangjun is correct, you can only interface MATLAB through COM, but you can control Simulink from MATLAB, which could be enough. The "open_system" and "close_system" will let you open and close model files, and the "sim" command will run them. In addition to this, the Configuration Parameters' "Import/Export" tab lets you control how/if the model's inports and outports read and write to the MATLAB workspace.

Thanks very much. Will look into that solution.
