Matlab
Setup
Go to http://neo4j.com/download and download, install and start neo4j 3.3.1.
After providing the initial password, choose a new password, you’ll need it later.
Type into the command-line at the top: :play movies, click the big block of text which is then copied into the command-line and hit the triangular "Run" button (or press Ctrl-Enter).
The data is inserted and should be visualized.
Get JDBC Driver
Download the Neo4j jdbc driver from neo4j-contrib/neo4j-jdbc GitHub releases Need the older version b/c MATLAB still runs on Java 7
curl -O "$HOME/Documents/MATLAB/neo4j-jdbc-driver-3.1.0.jar" https://github.com/neo4j-contrib/neo4j-jdbc/releases/download/3.1.0/neo4j-jdbc-driver-3.1.0.jar
Add the jar to the class pah via javaaddpath
javaaddpath([matlabroot,'/neo4j-jdbc-driver-3.1.0.jar'])
and check that the dynamic path contains the jar
javaclasspath
Test Connection
Open Connection
conn = database('','neo4j','test','org.neo4j.jdbc.BoltNeo4jDriver','jdbc:neo4j:bolt://localhost:7687')
Fetch Total Node Count
curs = exec(conn,'MATCH (n) RETURN count(*)') curs = fetch(curs); curs.Data close(curs)
Output
ans =
'102671'
Fetch Movies
curs = exec(conn,'MATCH (n:Movie) RETURN n.title, n.released, n.tagline') curs = fetch(curs).Data curs.Data close(curs)
Output
ans =
