You che explain the function?
I try this function and is good, but there are more values because it
done also only with the first value, the first and the second like so
in the last values. Is possibile done something to correct the
mistake?

the function done
y=[y1,y2,y3,y4,y5]
(0+0+y1)/4
(0+2*y1+y2)/4
