If you are using MATLAB R2011a, you can use Instrument Control Toolbox's TCPIP object as a Server Socket via the NetworkRole property. This support is for a single remote connection. You can use this connection to communicate between a client and MATLAB, or between two instances of MATLAB.

If you use the Instrument Control Toolbox, you can do this using udp. The Instrument Control Toolbox is, however, not able to send this data using tcp for this situation, as that toolbox does not allow MATLAB to be the "server" that connections are initiated to.

There is a MATLAB File Exchange contribution "tcpudpip" which is able to transfer data through udp or tcp; that contribution is able to have MATLAB act as a server.

Note: in the time since I wrote the above, Instrument Control Toolbox added a "server" role so it can now be done with tcp as well.

Set your terminator to byte rather than a particular character.

For those looking for;how can we sent an image from a computer to another over a network using the tcpip protocole, here is the code because it can be helpful for many people. To run: run the Server session and after that the client session:

Server Session:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
close all;clear all;clc;
data =imread('out1.jpg');
data=im2double(data);
s = whos('data')
s.size
s.bytes
tcpipServer = tcpip('0.0.0.0',30000,'NetworkRole','Server');
set(tcpipServer,'OutputBufferSize',s.bytes);
fopen(tcpipServer);
fwrite(tcpipServer,data(:),'double');
fclose(tcpipServer);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Client Session:

close all;clear all;clc;
tcpipClient = tcpip('172.17.94.29',30000,'NetworkRole','Client')
set(tcpipClient,'InputBufferSize',460800);
set(tcpipClient,'Timeout',30);
fopen(tcpipClient);
rawData = fread(tcpipClient,57600,'double');
fclose(tcpipClient);
reshapedData = reshape(rawData,120,160,3);
imshow(reshapedData)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Thanks a lot for those who are helping others.

Keep Going !!!!!!
