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.

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

nodeid = 2;

node = searchNodeByID(neo4jconn,nodeid);

Search for all incoming relationships for the node. nodereltypes returns a list of the relationship types.

nodereltypes = nodeRelationTypes(node,'in')
nodereltypes = 1×1 cell array

Close the database connection.


Input Arguments
