If i have the following data

time=[1 2 3 4 5] %time in seconds

acceleration=[1.1 1.2 1.3 1.4 1.5]

Then how can I integrate acceleration and get the velocity at every second in the form of an array.

I tried v=trapz(acceleration);

but that just integrates acceleration and returns a single value

Use cumtrapz instead.

Believe me: cumtrapz(time,acceleration) gives you the velocity field V with initial value V(time(1)) = 0.

If you do

(second element-first element)/time

you differentiate. But velocity is acceleration integrated.

oh I got it now thank you
