[Haskell-cafe] Help to create a function to calculate a n element moving average ??

[rgowka1]

Type signature would be Int -> [Double] -> [(Double,Double)]

Any thoughts or ideas on how to calculate a n-element moving average
of a list of Doubles?

Let's say [1..10]::[Double]

what is the function to calculate the average of the 3 elements?

[(1,0),(2,0),(3,2),(4,3)....] :: [(Double,Double)]

(1,0) the average is zero as the length is less than 3

(2,0) the average is zero as the length is less than 3

(3,2) the average is (1+2+3)/3 = 2

(4,3) the average is (2+3+4)/3 = 9
