Simulink - sum of elements in exact time

How to sum elements getting in exact time.

For example the simulation time is 60s and i measure the current and then write to file at every 1s (sample time 1).

*(s)(A)*

• 1 10
• 2 10
• 3 15
• . .
• . .
• 60 15

and my question is how to sum these Ampers and get one result. 10+10+15+..+15 = xxx

Use a discrete transfer function bloc set to:

Numerator=1
Denominator=[1 -1]
sample time=1

Helped me a lot, you made my day :) thank you!

I would like to ask you how it works. for example i have these inputs "1 2 3" and the formula look like this 1/z-1 and how it calculate the sum? What is "z" in this case? i have tried calculate it and i became with this "solution"

i think the z - transform formula in this case look like this:

1*1^(-1)+2*1^(-2)+3*1^(-3)=6

thank you
