This example shows how to move a requirement down in the hierarchy.

Load the crs_req_func_spec requirement file, which describes a cruise control system, and assign it to a variable. Find the requirement with index 3.1.

rs = slreq.load('crs_req_func_spec');
req1 = find(rs,'Type','Requirement','Index','3.1');

Move the requirement down one spot in the hierarchy. Confirm the move by checking the success status, tf1, and the index.

tf1 = moveDown(req1)
tf1 = logical
   1


req1.Index
ans = 
'3.2'

Find the requirement with index 3.4. This requirement is already at the bottom of its level in the hierarchy and cannot be moved down further, which you can verify by trying to move it down. Confirm that the move failed by checking the success status, tf2, and the index.

req2 = find(rs,'Type','Requirement','Index','3.4');
tf2 = moveDown(req2)
tf2 = logical
   0


req2.Index
ans = 
'3.4'
