This package provides the calculation engine for the [Brightway2 life
cycle assessment framework](https://brightway.dev). [Online
documentation](https://docs.brightway.dev) is available, and the source
code is hosted on
[Github](https://github.com/brightway-lca/brightway2-calc).

The emphasis here has been on speed of solving the linear systems, for
normal LCA calculations, graph traversal, or Monte Carlo uncertainty
analysis.

Relies on [bw_processing](https://github.com/brightway-lca/bw_processing)
for input array formatting.
