How can change the time domain data into length domain data?

Now I have a set of acceleration data in time-domain, the interval time (2s) and the speed (5 mm/s) are known. I want to ask, How can I change the acceleration data(time domain) into acceleration data (length-domain).

thanks for the helping. Regards.

As best I can understand, you want acceleration in terms of distance. I would use two cumtrapz integrations to get distance from acceleration:

dx2dt2 = 0:0.01:1;                      % Acceleration Vector
x = cumtrapz(cumtrapz(dx2dt2));         % Distance Vector

figure(1)
plot(x, dx2dt2)

Hi Star strider,

Thanks for your answer. I think I didn't present my question clearly. I will try to describe it in another way. Now, I have two sets of data A =[2,3,4,5,6,7,8,9,0,1]. and B =[1,2,3,4,5,6,7,8,9,0]. How can I create data C, which plot(C) is same as plot(B,A) .

That is not possible. The plot function will plot a (10x2) or (2x10) matrix ‘C’ that you create, but the plot will not look like plot(B,A). That is simply not how the function works.

Thanks for the answer. I understand it now. :D I wish you have a great day.

My pleasure.

I wish you the same.
