Create a Neo4j® 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® connection object neo4jconn. The blank Message property indicates a successful connection.

neo4jconn.Message

ans =

     []

Search the database for the node with node identifier 2 using the Neo4j® database connection neo4jconn.

nodeid = 2;
node = searchNodeByID(neo4jconn,nodeid);

Search for the degree of all incoming relationships for the node. degree returns a structure with the in-degree for each relationship type.

degree = nodeDegree(node,'in')

degree = struct with fields:
    knows: 1

Close the database connection.

close(neo4jconn)
