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?

I would guess you would want dt to be a column vector so it's the same shape and size as x and y and you will want to have it be the change in time, not absolute time.
