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.

[Walter Roberson]

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.

[Walter Roberson]

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.

Thanx Dear

I have learn it and trying do so.

for more help can i contact u ?

[Walter Roberson]

I haven't implemented this myself, but there are examples in the documentation.

I am facing an error

That is Warning: A timeout occurred before the Terminator was reached.

ans =

''

[Walter Roberson]

Set your terminator to byte rather than a particular character.

hi friends :)) , any one help me how to send a picture byyy socket(:'()) on a server and client matlabbb

[Walter Roberson]

See the documentation Ankit indicated. It has an example. In the example, the variable named "data" could be the raw bytes of the picture file, or it could be the image matrix you get from imread(). If you send the image matrix, be sure to send the image dimensions first so that the other end knows how to reshape the values received in to an appropriate matrix.

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 !!!!!!
