I'd say, 
classdef yourNodes
    properties
        S; % start nodes
        T; % end nodes
        pts; % points
    end
    methods
        function obj = addNode(obj, X, Y, Z)
            obj.pts = [obj.pts; X, Y, Z];
        end
        function obj = connectNodes(obj, ind1, ind2)
            obj.S = [obj.S, ind1];
            obj.T = [obj.T, ind2];
        end
    end
end
Then you could simply...
myNodes = yourNodes;
myNodes = addNode(myNodes, 1, 1, 1); % add node 1
myNodes = addNode(myNodes, 2, 2, 2); % add node 2
myNodes = connectNodes(myNodes, 1, 2); % Connect node1 to node2
