# SavitzkyGolayMatrix

SavitzkyGolayMatrix[r,k]

gives a matrix corresponding to a smoothing kernel of radius r for performing polynomial regression of degree k.

SavitzkyGolayMatrix[{r1,r2},{k1,k2}]

gives a matrix for performing polynomial regression of degree k1 over a window of radius r1 along rows, and degree k2 over a window of radius r2 along columns.

SavitzkyGolayMatrix[r,k,n]

gives a matrix for performing the n derivative of a polynomial regression of degree k.

SavitzkyGolayMatrix[{r1,r2 },{k1,k2,},]

gives an array using the specified parameters for each direction i.
