Time windows and time shift in an array of data

I have an array of data [1:120] and want to calculate sum of the elements in diffrent time windows and diffrent time shifts. For example, in case of 1 hour shift we have different time windows. [1,1], [1,2],[1,3],[1,4]..... [1,120] (here first element represent the tiem shift and second represent the length of time window).

the output (u) will be used in the formula

b=((u-(r).*(dt)./std

here r is fixed (say r=0.3333), std is fixed (say std=0.54644) dt is vary with the length of time winodw if length is 1 then dt=1 and so on.

May someone help me here...

Thank you

both are almost same but earlier answer not work
