Savitzky Golai Filter PtByPt (Not in Base Package)

Performs fitting based on a polynomial of a given order and then smoothes the curve instead of outputting raw data. Details

initialize, when TRUE, initializes the internal state of the VI.
input data is a set of input data.
nR=(-nL) sets data points on the right and data points on the left of the data currently under investigation. The whole history length is exactly 2*(nR=(-nL))+1. This number determines the amount of data used to fit the curve. For example, the default value 6 for nR=(-NL) generates a history length 2*(6)+1, or 13. The VI uses 13 points to fit the curve.
order polynomial is the order of the fitting model. The default is 3. In the case of the Savitzky Golai Filter PtByPt VI, the order is a polynomial. For example, when you set order polynomial to two, the VI uses quadratic fitting.
output data is the fitted and smoothed data.
error returns any error or warning condition from the VI. Refer to Point By Point Error Codes for more information about these conditions.
