This example shows how to set the attribute value of a specified custom attribute for a link.

Load the crs_req requirement files, which contain links for a cruise control system.

slreq.load('crs_req');
slreq.load('crs_req_func_spec');

Create a links array containing all links. Get one link from the array.

linksArray = slreq.find('Type','Link')

linksArray=1×12 object
  1x12 Link array with properties:

    Type
    Description
    Keywords
    Rationale
    CreatedOn
    CreatedBy
    ModifiedOn
    ModifiedBy
    Revision
    SID
    Comments

lk = linksArray(1);

Custom attribute Target Speed Change, tracks whether the linked requirements are related to incrementing or decrementing the speed, or not related at all. Set the value of Target Speed Change to Unset for your link. Then use getAttribute to confirm that the value was set correctly.

setAttribute(lk,'Target Speed Change','Unset');
value = getAttribute(lk,'Target Speed Change')

value = 
'Unset'

slreq.clear;
bdclose all;
