m = mobiledev
m.AngularVelocitySensorEnabled = 1;
m.OrientationSensorEnabled = 1;
m.Logging = 1;
pause(15)
m.Logging = 0;
[av, tav] = angvellog(m);
[o, to] = orientlog(m);
yAngVel = av(:,2);
roll = o(:, 3);
plot(tav, yAngVel, to, roll);
legend('Y Angular Velocity', 'Roll');
xlabel('Relative time (s)');
tInit = datetime(m.InitialTimestamp, 'InputFormat', 'dd-MM-yyyy HH:mm:ss.SSS');
tAngVel = tInit + seconds(tav);
tOrient = tInit + seconds(to);
yAngVelDeg = yAngVel * 180/pi;
plot(tAngVel, yAngVelDeg, tOrient, roll);
legend('Y Angular Velocity', 'Roll');
xlabel('Absolute time (s)');
m.AngularVelocitySensorEnabled = 0;
m.OrientationSensorEnabled = 0;
clear m;
