LOOKUP Y-VALUE FROM A GIVEN X-VALUE¶
Performs a point lookup on one or more curves, returning the interpolated y-value at a specified x-value. Use this worker whenever you need to extract a single response value (e.g. force, displacement, acceleration) at a known abscissa from a curve dataset.
When to use¶
Classification: process.
Tagged: curve, interpolation, lookup, point-query, x-value, y-value.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curves To Be Looked Up | curvestobelookedup | vector | — | ✓ | One or more input curves (x–y pairs) from which the y-value will be interpolated; accepts a vector of curve objects — provide at least one curve, multiple curves are processed independently. |
| X Value | x_value | float | 0.0 | ✓ | The x-axis position (float, same units as the curve’s x-axis) at which the corresponding y-value is to be looked up; defaults to 0.0. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_lookup_yvalueat_output_1 | curves_lookup_yvalueat_output_1 | dataset | A dataset containing one row per input curve with the curve identifier and the interpolated y-value found at the specified x-value. |
