# Basic Sums package¶

This guide is intended to make you familiar with the basicsums package for computing structural sums (also known as basic sums), mathematical objects originating from the theory of composites, considered to form a feature space vector of data represented by points or disks on the plane.

Structural sums have proven their value as geometric parameters describing random distributions of disks on the plane. They also perform the same role in description of microstructure as the $$n$$-point correlation functions.

See short introduction on the general structure of the package, installation, and applications. Then you may proceed with Tutorial, where the functionality of the package was described in details by examples. Refer also to the Theory overview section covering the underlying theory, for better understanding the package’s purposes.

The repository with the source code for basicsums package is available at the Bitbucket .
