Detailed Description

Unit aggregation utility.

Provides functions for updating and calculating effective units from a stack of unit-exponent pairs. Matching units are aggregated, where a standard unit simplifies access when joining exponents. The utility is used in the context of effective reaction rate units.

Note: Helper utility class for internal use within Cantera.

Warning: This class is an experimental part of the Cantera API and may be changed or removed without notice.
