Hi,
I have some accelration data from an IMU and would like to get velocity and distance.
How could I do that?
Thanks in advance
figure
plot(dugyro,IMU_AccZ)
title('Acc Z - Raw Data')
ylabel("(m/sec/sec)")

You could use cumtrapz(), twice.
Caution: using numeric integration to calculate distance and velocity is rather prone to error.

Even the best accelerometers, with a standard error of 10 micro-g, would accumulate a 50-meter error within 17 minutes

ds = seconds(dugyro);
Vel = cumtrapz(ds, New_IMU_AccZ);
dist = cumtrapz(ds, Vel);
