.. _auto_definetable_get_max_value:

*RETURN THE MAX OF ALL VALUES*
==============================

Scans all numeric values in a define_table (value/curve pair table) and returns a new define_table containing only the entry with the maximum value. Use this worker when you need to identify the peak value across a parameter table within a workflow.
