Integrating velocity data with cumtrapz()

Hi,

I have a quite long vector with the longitudinal velocity data of a car. As it only drives forward, there are no negative values. However, when I integrate the vector using cumtrapz() the calculated data which are supposed to be the traveled distance, are also decreasing and even becoming negative.

Used Timestamps for cumtrapz are 0:0.01:59.53 The velocity vector is attached.

Thanks in advance! -Fabian

Seems to work fine for me:

x = 0:0.01:59.53;
Q = cumtrapz( x, chassis_velocity_longitudinal );
figure; plot( x, Q )

Oh god, I accidentally switched time and velocity.. Sorry for this embarrassing question and thanks for the quick help!

Kind regards -Fabian
