+%% X-Plane Connect MATLAB Recording Example Script
+% This script demonstrates how to record data from X-Plane that can later
+% be played back. (See Playback.m)
+% Before running this script, ensure that the XPC plugin is installed and
+% X-Plane is running.
+%% Import XPC
+addpath('../')
+import XPlaneConnect.*
+
+%% Setup
+% Create variables and open connection to X-Plane
+path = 'MyRecording.txt'; % File to save the data in
+interval = 0.1; % Time between snapshots in seconds
+duration = 10; % Time to record for in seconds
+Socket = openUDP(); % Open connection to X-Plane
+fd = fopen(path, 'w'); % Open file
+
+disp('X-Plane Connect Recording Example Script');
+fprintf('Recording to ''%s'' for $f seconds in %fs increments.\n', path, duration, interval);

+%% Start Recording
