How to create a blank SLMX file?

I would like to create a blank SLMX file and then program it from scratch. How can I accomplish this workflow?

As of R2022b, a direct method to manually create SLMX files is not available.

When you create a requirements link ("slreq.Link" object) from a Simulink object (source artifact) to a requirement, Requirements Toolbox™ automatically creates a link set ("slreq.LinkSet" object) and saves it as an SLMX file in the same folder as the source artifact.

One indirect way to create a blank link set is to create a mock link and delete it later. A blank link set file can be created for a loaded Simulink model using following script:

 

% Create a mock requirement set with single Requirement
rs = slreq.new('mockName')
r1 = add(rs)

% Create a temporary link to mock requirement
l1 = slreq.createLink(gcb, r1)
ls = l1.linkSet

% Delete the temporary link
l1.remove()

% Discard the mock requirements
r1.remove()
rs.discard()

% Save the link set file
ls.save()

For more information on "slreq.Link" and "slreq.LinkSet" objects, please refer to the following documentation:
