.. _auto_curve_power:

*COMPUTE THE Y-POWER OF THE CURVE*
==================================

Raises the y-values of a curve to a specified numeric exponent, leaving x-values unchanged. Use this worker to apply a power transformation to any (x, y) curve within a workflow.

When to use
-----------

Classification: **process**.

Tagged: ``curve``, ``exponent``, ``math``, ``power``, ``transformation``, ``y-transform``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

     - Required
     - Description
   * - Curve
     - input_curve
     - vector
     - —
     - 
     - The input (x, y) curve whose y-values will be raised to the given power; accepts any vector curve type.
   * - Power Exponent
     - power
     - scalar
     - 1
     - 
     - Scalar exponent applied to every y-value of the curve (e.g. 2 for squaring, 0.5 for square root); defaults to 1 (no change).
