MovingMap

MovingMap[f,data,w] applies f to size w windows in the specified data.

MovingMap[f,data,wspec] uses windows specified by wspec.

MovingMap[f,data,wspec,padding] pads data using padding.

Examples

Compute a moving average:

MovingMap[Mean, {1, 2, 3, 4, 5, 6}, 3]
(* {2, 3, 4, 5} *)

Apply a function to sliding windows:

MovingMap[Total, Range[10], 4]
(* {10, 14, 18, 22, 26, 30, 34} *)
