TCPIP Socket with Matlab 2011b

Hello,

I would like to communicate with my device with sockets by using TCPIP.

With Matlab R2018b, I was just using the command :

error_detector = tcpip('10.194.64.26',5001);

However, I've had to go back on a older version of Matlab (R2011b) and this command doesn't work anymore.

Do you know an equivalent of tcpip?

Thanks,

Dylan
