.. _auto_curves_abs:

*COMPUTE THE ABS VALUE OF THE CURVES*
=====================================

Computes the element-wise absolute value of one or more input curves, transforming all negative Y-values to their positive equivalents. Use this worker whenever signed curve data (e.g. force, displacement, acceleration) needs to be rectified before further processing.

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

Classification: **process**.

Tagged: ``abs``, ``absolute_value``, ``curve_transform``, ``rectify``, ``signed_data``.

     - 
     - One or more input curves whose Y-values will have the absolute value applied; accepts any signed numeric curve (e.g. force, displacement, acceleration). Optional — if omitted the worker passes through without output.

Outputs

   * - curves_abs_output_1
     - curves_abs_output_1
     - vector
     - Resulting curves after element-wise absolute value has been applied to all Y-values; X-axis is unchanged and the output curve count matches the number of input curves.
