libxnd is a lightweight library for initializing and managing typed memory blocks. It relies on the libndtypes library for typing and traversing memory.

The xnd Python module implements a container type that maps most Python values relevant for scientific computing directly to typed memory.

Whenever possible, a single, pointer-free memory block is used.

xnd supports ragged arrays, categorical types, indexing, slicing, aligned memory blocks and type inference.

Operations like indexing and slicing return zero-copy typed views on the data.

libxnd/xnd was created by Stefan Krah. The funding that made this project possible came from Anaconda Inc. and currently from Quansight LLC.
