Welcome to npdict’s documentation!

npdict is a Python package for dictionary wrappers for NumPy arrays. It aims at facilitating holding numerical values in a Python dictionary, while retaining the ultra-high performance supported by NumPy.

It supports an object which is a Python dictionary on the surface, but NumPy behind the back, facilitating fast assignment and retrieval of values and fast computation of NumPy arrays.
