link to a m-file from Simulink model

Hi,

How can I place a box with the link to a m-file into a Simulink model like those of S-function examples ?

Thanks

Are you talking about sfundemos.mdl?

Yes

[Fangjun Jiang]

What do you mean "link"? What do you try to do? There is a way to run a .m file when you double-click a block in the Simulink model. But that is not the case for sfundemos.mdl. It's just a library with subsystem hierarchy.

Hello can you please tell me how can i run .m file when i double clicl a simulink model.

I think the links in the S-function demos are basically empty subsystems with the OpenFcn block callback defined so as to open the corresponding MATLAB file. You can drag a Subsystem block, delete its contents so the input/output ports disappear. Then right-click on the block, select "Block Properties" and under the Callbacks->OpenFcn pane, enter "edit mymatlabfile.m". This should do the trick.

The other technique as Alessandro mentioned is to create an annotation and define it's ClickFcn as "edit mymatlabfile.m".

Thanks for reply,

I thought 'annotation properties' setting was the easiest method.

I'll try with OpenFnc.
