minterpy.utils

The utility sub-package used across Minterpy.

The utility functions are organized into modules based on the context in which they are used. For example, utilities related to the Newton polynomial are located in the minterpy.utils.polynomials.newton module.

This organization prevents utility modules from being scattered across various Minterpy sub-packages. Although a utility module may suggest that the functions within are generic, they are usually specific to a particular context.

Moreover, these functions are organized not only because they may be used in multiple places, but also to represent a distinct layer of abstraction. These functions operate on lower-level data structures, predominantly NumPy arrays, and do not assume any knowledge of higher-level constructs from the Minterpy abstraction, such as instances of concrete polynomials, MultiIndexSet, or Grid.
