Savitzky-Golay Filter Design (G Dataflow)

A Boolean that determines whether the node calculates the differentiation filters.

Default: True

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.

Default: 6

Order of the polynomial.

Default: 3

Weighting vector to use in the least squares minimization.

This array must be empty or have a length of side points*2 + 1.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

A matrix with rows representing the FIR filter coefficients.

The matrix is n-by-n, where n is side points*2+1.

A matrix where the p-th row is the differentiation filter for the p-th order derivative.

The matrix is m-by-n, 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.

Error information.

The node produces this output according to standard error behavior.
