sumsStaticInt :: C v => Int -> T v -> T vSource
Like Synthesizer.Plain.Filter.NonRecursive.sums
but in a recursive form.
This needs only linear time (independent of the window size)
but may accumulate rounding errors.
ys = xs * (1,0,0,0,-1) / (1,-1) ys * (1,-1) = xs * (1,0,0,0,-1) ys = xs * (1,0,0,0,-1) + ys * (0,1)
