How make code has 2 vectors as input and make loop than find output as vector

Hi everyone.

I need know how I can make code I can put two vectors and use them in loop to find another vector as output.

So, for make clear. I have two vectors one of them is time (s), and another one is v ( ft/s ). I want make loop to find acceleration = (V1-V0)/(t1-t0).

Thank you

v=rand(10,1);
t=[0:0.1:0.9]';
a=zeros(numel(v),1);
for ii=2:numel(v)
    a(ii,1)=(v(ii)-v(ii-1))/(t(ii)-t(ii-1));
end
disp('Acceleration:')
a

Thank you. I my v vector is v=[ 0,44,67,34] how I can put this vector?

Isn’t this homework?

No, because I had problem about how make loop with vectors. I know now how you made this. Thank you so much. Now I can finish my work.?? However, I have last question about this line ii=2:numel(v) why you put just v not t ?

[Raj]

Because both are supposed to have same number of elements. So you can use either of them here.

In you case you have mentioned v=[ 0,44,67,34] so t=0:dt:Tf where dt is your sampling time and Tf is your end time. Everything else remains the same.
