Hello;

I am inexperienced in coding. I would like to get acceleration-time history from displacement-time history. The displacement-time history is attached. Can anyone help me out please? Thank you.

I am inexperienced in coding. I need to double integrate to get disp from acceleration-time history or double differentiate to get acceleration from displacement-time history. I have tried following code in the link, but somehow I failed. I have displacement history with time increment of 0.08 sec and correspondent disp(mm). And one acceleration-time history with time step of 0.0195 sec.
