Hi Ehsan,
What version of MATLAB are you using?
Can you post snippet of your code that is running into errors?

hi dear
thanks for your attention

yeah
this file is about connecting flightgear to simulink
function wp_dist_m =get_wpdist(host, port)
% [WP_DIST_M]=GET_WPDIST(HOST, PORT)
%
% Read distance WP_DIST of aircraft from current waypoint in
% Flightgear over socket connection (HOST, PORT).
% Run Flightgear on HOST (e.g. '127.0.0.1' = localhost) with
% parameter "--props = PORT".
import java.net.Socket
import java.io.*
fg_socket = Socket(host, port);
out = PrintWriter(fg_socket.getOutputStream(), true);
in = BufferedReader(InputStreamReader(fg_socket.getInputStream()));
% waypoint distance meter
out.println(sprintf('get /autopilot/route-manager/wp/dist\r\n'));
wp_dist_m_str = char(in.readLine());
j = strfind(wp_dist_m_str,'''');
%Conversion from sea miles (nm) to meter
wp_dist_m = str2double(wp_dist_m_str(j(1)+1:j(2)-1)) * 1852;
out.close();
in.close();
fg_socket.close();
end
