MATLAB: Integration of displacement to velocity then acceleration

integrationnumerical integration

I want to integrate this displacement vector (jh) to get velocity and then to get acceleration.
There are multiple trials of which I need to integrate from. when i do:
%%Calculation of Velocity and Acceleration

        v= trapz (jh);
        a= trapz (v);
this gives an output for the V but not for the A. When I do cumtrapz below:
%%Calculation of Velocity and Acceleration
        v= cumtrapz (jh);
        a= cumtrapz (v);
This is a cumulative integration and this is not what I want

Don't you mean take the derivative of displacement with respect to time to get velocity and again for acceleration?
