No connection between Matlab 2013a 64bit and EV3

Hello,

I've got a problem connecting an EV3 with Matlab. I've already embedded the required package but I always get a failure when I try to connect to Matlab.

When I try to connect via Bluetooth, it says:

>> b = Brick('ioType','bt','serPort','com6')

b = 

    Brick with properties:

           conn: [1x1 btBrickIO]
          debug: 0
         ioType: 'bt'
       btDevice: []
      btChannel: []
         wfAddr: []
         wfPort: []
           wfSN: []
        serPort: 'com6'

>> instrfind

        ValuesSent:         0

>> name = b.getBrickName()
No appropriate method, property, or field getBrickName for class
Brick.

Do you have any idea what I can try to get a connection?

Thanks in advance,

Carsten
