This example shows how to get and delete orphan links.

Load the myAddRequirements requirement set, which contains requirements for a MATLAB® function that adds two inputs and outputs the result.

rs = slreq.load("myAddRequirements");

The myAddRequirements requirement set has incoming links from lines of code in the myAddOrphan MATLAB code file. Get a handle to the link set.

myLinkSet = slreq.find(Type="LinkSet");

Get the orphan links in the link set. Display the number of orphan links.

orphanLinks = getOrphanLinks(myLinkSet);
numOrphanLinks = numel(orphanLinks)
numOrphanLinks = 1

Delete the orphan links.

count = deleteOrphanLinks(myLinkSet)
count = 1

Confirm that there are no orphan links.

orphanLinks = getOrphanLinks(myLinkSet)
orphanLinks =
