    %% Search Graph by Relationships
% Create a Neo4j(R) database connection using the URL
% |http://localhost:7474/db/data|, user name |neo4j|, and password |matlab|.
url = 'http://localhost:7474/db/data';
username = 'neo4j';
password = 'matlab';

neo4jconn = neo4j(url,username,password);

%%
% Check the |Message| property of the Neo4j(R) connection object
% |neo4jconn|.

neo4jconn.Message

%%
% The blank |Message| property indicates a successful connection.

%%
% Search the graph for the relationship type |'knows'| using the Neo4j(R)
% database connection |neo4jconn|.

%%
% |graphinfo| is a structure that contains the results of the search:
%%
% * |Nodes| -- A table containing all starting and ending nodes that denote
% each matched relationship.
% * |Relations| -- A table containing all matched relationships.

%%
% Access the table of nodes.

graphinfo.Nodes

%%
% Access the table of relationships.

graphinfo.Relations

%%
% Search the graph for all relationship types in the database.
