请教大神，
function server(message, input_port, number_of_retries)
import java.net.Socket
import java.net.ServerSocket
import java.io.*

if (nargin < 3)
      number_of_retries = 20; % set to -1 for infinite
end
retry          = 0;

server_socket  = [];
input_socket  = [];
server    = [];
while true

      retry = retry + 1;

      try
         if ((number_of_retries > 0) && (retry > number_of_retries))
            fprintf(1, 'Too many retries\n');
            break;
         end

         fprintf(1, ['Try %d waiting for client to connect to this ' ...
                     'host on port : %d\n'], retry, input_port);%listen

         % wait for 1 second for client to connect server socket
         server_socket = ServerSocket(input_port);
         server_socket.setSoTimeout(1000);

         input_socket = server_socket.accept;

         fprintf(1, 'Client connected\n');%acceppt
         pause(1.5);
         % get a buffered data input stream from the socket
         input_stream = input_socket.getInputStream;%获得网络连接输入，返回inputstream
         d_input_stream = DataInputStream(input_stream);

         % read data from the socket - wait a short time first
         pause(4.5);
         bytes_available = input_stream.available;
         fprintf(1, 'Reading %d bytes\n', bytes_available);

         server= zeros(1, bytes_available, 'uint8');
         for i = 1:bytes_available
            server(i) = d_input_stream.readByte;
         end

         server = char(server);

      %接收结束关闭socket
      catch
         if ~isempty(server_socket)
            server_socket.close
         end

         if ~isempty(input_socket)
            input_socket.close
         end

         % pause before retrying
         pause(1);
      end
end
end
此程序运行后能得到读取到数据了，那么数据是在input_stream里吗？怎么把里面的数据显示到GUI上？非常感谢！

你这参数定义的不对。
