*ENFORCE DECAY - MONOTONICALLY DECREASING VALUES FOR Y*
=======================================================

Processes a curve so that its Y-values are monotonically decreasing, enforcing a strict decay profile by replacing any non-decreasing values. Use this worker when downstream analysis requires a guaranteed decay curve, such as S-N fatigue or material softening data.

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

Classification: **process**.

Inputs

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

   * - Label

     - Required
     - Description
   * - Curve 1
     - curve1
     - vector
     - —
     - 
     - Input XY curve whose Y-values will be processed to enforce monotonic decay; any Y-value greater than its predecessor will be corrected. Optional — leave unconnected if supplying the curve via a chained upstream worker.

Outputs

   :header-rows: 1
   :widths: 20 20 20 20

   * - Label

   * - curve_enforce_decay_output_1
     - curve_enforce_decay_output_1
     - vector
     - Output XY curve with the same X-values as the input but with Y-values adjusted so they are monotonically non-increasing from the first point to the last.
