COMPUTE THE Y-DIFFERENCE COMPARED TO THE PREVIOUS POINT¶
Computes the y-difference between each point and its immediately preceding point for one or more input curves, appending the delta as a new curve. Use this worker when you need a discrete first-difference (delta-y) representation of a signal along its x-axis.
When to use¶
Classification: process.
Tagged: curve-transform, delta, difference, first-difference, point-wise, y-diff.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve In | curves | vector | — | One or more input curves (x/y vector pairs) for which the y-difference relative to the previous point will be computed; accepts multiple curves in batch. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_add_output_1 | curve_add_output_1 | vector | Output curve(s) containing the point-wise y-difference values (y[i] − y[i−1]) at each x position; the first point is typically zero or dropped depending on implementation. |
