Designs a Savitzky-Golay FIR smoothing filter, returning the designed Savitzky-Golay filter coefficients and the differentiation filter coefficients.
compute differentiation filters?
A Boolean that determines whether the node calculates the differentiation filters.
||The node calculates the differentiation filters.
||The node does not calculate the differentiation filters.
The number of data points to each side of the current data point to use for the least squares minimization. side points*2 + 1 is the length of the moving window, which must be greater than the polynomial order.
Order of the polynomial.
Weighting vector to use in the least squares minimization. This array must be empty or have a length of side points*2+1.
An n-by-n matrix with rows representing the FIR filter coefficients, where n is side points*2+1.
An m-by-n matrix where the p-th row is the differentiation filter for the p-th order derivative, where m is polynomial order+1, and n is side points*2+1.
This node computes differentiation filters only if compute differentiation filters? is TRUE.
A value that represents any error or warning that occurs when this node executes.
