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.
