Bottlechest is a fork of bottleneck (, specialized for use in Orange (

Transition has not been completed yet, and the project mostly refers to itself as bottleneck, for now.

Moving window functions, several other functions and all optimization of 3d arrays are removed to reduce the size of the library. New functions are added as needed.

NumPy/SciPy median, nanmedian, rankdata, ss, nansum, nanmin, nanmax, nanmean, nanstd, nanargmin, nanargmax
Functions nanrankdata, nanvar, replace, nn, anynan, allnan, nanequal

For other documentation, including a simple example and comprehensive set of benchmarks, refer to the original project.
