python3-numpy-groupies binary package in Ubuntu Mantic amd64
This package consists of a couple of optimised tools for doing things
that can roughly be considered "group-indexing operations". The most
prominent tool is `aggregate`.
.
`aggregate` takes an array of values, and an array giving the group
number for each of those values. It then returns the sum (or mean, or
std, or any, ...etc.) of the values in each group. You have probably
come across this idea before, using `matlab` accumarray, `pandas`
groupby, or generally MapReduce algorithms and histograms.
.
There are different implementations of `aggregate` provided, based on
plain `numpy`, `numba` and `weave`. Performance is a main concern, and
so far this implementation comfortably beats similar implementations in
other packages (check the benchmarks).
