Hello,

I have some velocity (seismic) data and i want to convert them to displacement.

The sampling rate is 1000Hz so that means that if I want to find the displacement for 1 sec

I have 1000 values.

There is a list of commands that I can use but I am not sure which one suits to my case.

I just need to convert a list of data.

Any proposals?

Use cumtrapz as in

displacement = cumtrapz(velocity)/fs; % where fs is your sampling rate

Then you can assess afterwards if the accuracy is suitable for your application or whether you need a different method.
