Load the crs_req requirement file, which describes a cruise control system, and assign it to a variable. Find the referenced requirement with index 3, as this referenced requirement has child referenced requirements.

rs = slreq.load('crs_req');
parentRef = find(rs,'Type','Reference','Index','3')
parentRef = 
  Reference with properties:

              Id: 'Functional Requirements'
