steenroder_cpp is a C++ library for the computation of persistent steenrod barcodes inspired
by PHAT available under the GPLv3 license. It was written by Guillaume Tauzin as part of a
collaboration with Anibal Medina-Mardones and Umberto Lupo. See https://github.com/Steenroder/steenroder
for a high-performance python package.
The widespread use in applied topology of the barcode of filtered cellular complexes rests on a balance between discriminatory power and computability. It has long been envision that the strength of this invariant could be increase using cohomology operations. This package computes the recently defined Sqk-barcodes which have been shown to effectively increase the discriminatory power of barcodes on real-world data.
For a complete presentation of these invariants please consult Persistence Steenrod modules by U. Lupo, A. Medina-Mardones and G. Tauzin.

steenroder_cpp requires a C++14 compiler and cmake. Here is how to obtain, build, and
run steenroder_cpp:
`sh
git clone [email protected]:Steenroder/steenroder_cpp.git
cd steenroder_cpp
(mkdir -p build && cd build && cmake .. && make stn_double_2 && ./src/stn_double_2 ../examples/rp2.phat rp2_test)
