How to find acceleration from velocity and time data ?

I have csv file with one column of displacement (11130x1) and another of velocity (11130x2). Time difference between two immediate velocities is 0.01 sec. How can I find acceleration from velocity and time in column next to velocity column.

Assuming you have exported velocity data from the csv file using xlsread or something and saved it in a variable, say, 'vel'. To find acceleration you should know that acceleration is the change of velocity per unit time. So,

Now, let's calculate numerator of the RHS:

dV = gradient(vel);

and denominator is the time difference between successive velocity reading. So,

dt = 0.01; % sec

Now, acceleration LHS will become:

acceleration = dV./dt;

Now, you can easily import this acceleration data to the csv file using xlswrite or something. Let me know if you have any doubts in the future
