Running MATLAB command that awaits a later command; all in a script

Question

This is a question to an earlier question I had posted it turn out I need to generalize it. So I have these commands:

tracker=tcpip('127.0.0.1', 20200, 'NetworkRole', 'server');
fopen(tracker);
system('"C:\PROGRA~1\..." param1 param2')

I am using the same computer to be a listening server and a client as communication of an external device to the computer. The issue is the tracker server is waiting for the client to be started (system command).

Any feedback? Thanks

It is not possible to do it in a single script. The function fopen(tracker) will always wait for a connection. This is because it is supposed that the following instructions will be executed for a client.

Your code is saying: "Wait until a new connection is stablished (fopen). Then create a new client (system)". This doesn't make sense, so you should execute the client from a different script or program.

You can check it in the Matlab information: http://www.mathworks.es/es/help/instrument/using-tcpip-server-sockets.html

As you can see they specifically say:

MATLAB Client: This code is running on a second copy of MATLAB.

Thanks! Wow I have completely missed that comment. Okay, if run a second copy of Matlab is there still a method to automate the starting of the server and the client. – theAngryPhysicist Mar 27 '14 at 09:56
So now I am thinking if it's possible to start another session of Matlab with a time delay that will allow the server and the client to start consecutively. – theAngryPhysicist Mar 27 '14 at 10:00
Are you using Windows or Linux? – phyrox Mar 27 '14 at 10:41
