You've been asking a lot of questions about how to manipulate graph objects in MATLAB. If you haven't already I strongly recommend you read through each of the Topics listed on the main Graph and Network Algorithms documentation page. Once you've gone through this (particularly the Modify Nodes and Edges of Existing Graph topic) I think you'll find it much easier to work with your graph objects.
