Function: savitzkyGolay()

function savitzkyGolay(
   values, 
   window?, 
   order?): Float64Array;

Defined in: stats/signal.ts:113

Savitzky–Golay smoothing: least-squares fit a polynomial over a sliding window. Unlike a moving average it preserves peak height and width, which is why spectroscopy and sensor pipelines reach for it.

window must be odd (rounded up) and larger than order. Edges are handled by clamping to the nearest sample.
