How can I reference a Simulink signal line easily?

When you want to reference a block in a model you can use the full path to the block. For example, if you wanted to embed a link to highlight a block in f14, you can do this:

disp(['<a href="matlab:hilite_system(''f14/Stick Input'')">test1</a>']);

But the same is not true for lines. The best you can do now is this:

ports = get_param(get_param('f14/Gain','Handle'),'PortHandles'); 

lh=ports.Outputs(1); 

disp(['<a href="matlab:hilite_system(' sprintf('%1.15f',lh) ')">test</a>']);

The problem is that this does not persist if the model is closed and reopened.

There is no direct way of referencing to a Simulink signal in a model.

As a workaround , you can use the helper function (getOutputSignal) attached to this solution that would allow you to specify block and port (input/output, and port number), and then outputs a solid path to the line.

For instance, you can create a hyperlink to a Simulink signal line in the F14 model to the output of the Gain block using the following command:

open_system('f14');

disp(['<a href="matlab:hilite_system(getOutputSignal(''f14/Gain'',1))">test</a>']);
