I am new to this aurdhino stuff so cant find a way to comunicate betwen aurdhino and a tcp/ip server in matlab. looked up few things like UDP but that also didn`t help much! If any of you guys can help me out here or point me in right direction i would realy appreciate tht

Assuming you're using ethernet, take a look at this example

Just replace the "GET.." string with whatever you you want to send
