Can't call send from JeroMQ library integrated with Matlab.

I have some simple code that imports the JeroMQ jar file, and I'm able create a context, a socket, and a message, but when I go to send the message, I get the following error message even though when I tab-complete command. I see send as a valid function.

To use 'send', at least one of the following products must be licensed, installed, and enabled:
  Parallel Computing Toolbox
  Robotics System Toolbox

Here is the code boiled down to its simplest form:

      import org.zeromq.ZMQ
      ip = '192.168.1.20'
      ZMQ_MSG_PORT='50001'
      ctx = zmq.Ctx();
      message = zmq.Msg(); 

      cmdsocket = ctx.createSocket(ZMQ.REQ);

      cmdsocket.connect(['tcp://' ip ':' ZMQ_MSG_PORT]);

      cmdsocket.send("Hello",0);

It seems to me that there is some sort of path issue or something, because I am able to run the connect functions and the socketCreate functions. Any help is VERY MUCH appreciated.

I know I'm late to the party, but for anyone else with this problem, I solved it by using these imports instead:

import org.zeromq.*

import java.lang.*

After this fix, matlab no longer interprets zmq.send() as an overloaded function from control toolbox.

Hope it helps!
