This example shows how to get and update the requirement sets registered in a link set.

Open the Requirements Definition for a Cruise Control Model project.

slreqCCProjectStart;

Load the crs_req requirement set, which describes a cruise control system. This action also loads the crs_req link set and the crs_req_func_spec requirement set.

slreq.load("crs_req");

Find the crs_req link set and the crs_req_func_spec requirement set.

myLinkSet = slreq.find("Type","LinkSet","Name","crs_req");
rs = slreq.find("Type","ReqSet","Name","crs_req_func_spec");

Get the requirement sets registered in the crs_req link set.

registeredReqSets = getRegisteredReqSets(myLinkSet);

Get the links from the crs_req link set. Remove all of the links from the crs_req link set and close the crs_req_func_spec requirement set.

links = getLinks(myLinkSet);
for i = 1:numel(links)
    remove(links(i));
end
close(rs);

Update the requirement sets registered to the link set crs_req. Confirm that the requirement set crs_req_func_spec is not registered in the link set crs_req by getting the currently registered requirement sets.

updateRegisteredReqSets(myLinkSet)
registeredReqSets = getRegisteredReqSets(myLinkSet)
registeredReqSets =

  0x0 empty cell array

Cleanup

Clear the open requirement sets and link sets. Close the Requirements Definition for a Cruise Control Model project.

slreq.clear;
close(currentProject);

Tips

  • When you create a link to a requirement, the requirement set of the requirement becomes registered to the link set of the link. You can get the currently registered requirement sets for the link set by using getRegisteredReqSets. For more information, see Load Registered Requirement Sets.

  • You can only unregister a requirement set that is not loaded.

  • Loading the link set loads the requirement sets registered to that link set. For more information, see Load and Resolve Links.
