Hi, some time ago I download from this exchange this code:

Server:

data =imread('ngc6543a.jpg');
data=im2double(data);
s = whos('data');
s.size;
s.bytes;

tcpipServer = tcpip('...', 30000, 'NetworkRole', 'Server');
set(tcpipServer, 'OutputBufferSize', s.bytes);

fopen(tcpipServer);
    fwrite(tcpipServer, data(:), 'double');
fclose(tcpipServer);

Client:

tcpipClient = tcpip('...',30000);

set(tcpipClient,'InputBufferSize',300000);

set(tcpipClient,'Timeout',5); %Waiting time in seconds to complete read and write operations

fopen(tcpipClient);

get(tcpipClient, 'BytesAvailable');
tcpipClient.BytesAvailable 

DataReceived =[];
 pause(0.1);

while (get(tcpipClient, 'BytesAvailable') > 0) 
    tcpipClient.BytesAvailable
    rawData = fread(tcpipClient,300000/8,'double');
    DataReceived = [DataReceived; rawData];
    pause(0.1)
end

fclose(tcpipClient);
delete(tcpipClient); 
clear tcpipClient 

% ploting
reshapedData = reshape(DataReceived,650,600,3);
imshow(reshapedData)
