Description
Calculates derivative for data samples at point t with smoothing.
Syntax
=PO.Math.DataDiff(x_values, y_values, t, l)Parameters
| Parameter | Description |
|---|---|
| x_values | Sample points (N), sorted ascending. |
| y_values | Sample values (N) of each segment starting at the corresponding sample point. |
| t | Point t to calculate derivative at. |
| l | Minimum distance between abscissa of the points and that of point t, l=0 for no smoothing, [dimensionless]. |
