convert velocity to displacement

Hello All, I have test data in the vector form i.e. I have one vector with time and other vector with velocity. How can I convert it into displacement? Simple multiplication(displacement=velocity.*time) doesn't work much as it increases. Can someone help me? Thanks in advance

Displacement counts as the time integral of velocity.

Displacement in time:

data = [linspace(0,10,100)' rand(100,1)];
cumtrapz(data(:,1),data(:,2))

Total displacement:

trapz(data(:,1),data(:,2))
