Start a persistence service that uses Redis™ as the persistence provider. The service requires a connection name and an open port. Once the service is running, you can connect to the service using the connection name and create a cache.

ctrl = mps.cache.control('myRedisConnection','Redis','Port',4519);
c = mps.cache.connect('myCache', 'Connection', 'myRedisConnection');

Add keys and values to the cache.

put(c,'keyOne',10,'keyTwo',20,'keyThree',30,'keyFour',[400 500],'keyFive',magic(5))
