💖 ripser-coeff 💖

okay bestie, so this is a page from the General Commands Manual, and the command is ripser-coeff — aka the moment your flag complex persistent homology gets ✨coefficients✨. She computes persistent homology of flag complexes fast, and she does it over a field of your choosing. Not just any field. Your field. Periodt.

🌸 NAME 🌸

ripser-coeff — fast computation of persistent homology of flag complexes, with coefficients in chosen field 💅

---

🎀 SYNOPSIS 🎀

ripser-coeff [options...] [filename]

so it's literally options, then a filename, and the filename is vibing in brackets because she's optional. iykyk.

✨ OPTIONS ✨

• --help — show the help message and dip. that's it. that's the whole option. bye 👋
• --format <format> — tell her what the input file format is. the choices are, in order:
  • lower-distance — lower triangular distance matrix. this is the default, so if you say nothing she assumes this one 🫶
  • upper-distance — upper triangular distance matrix
  • distance — full distance matrix
  • point-cloud — point cloud in Euclidean space 🌈
  • dipha — distance matrix in DIPHA file format
  • sparse — sparse distance matrix in sparse triplet format
  • binary — lower triangular distance matrix in binary format 💀
• --dim <k> — compute persistent homology up to dimension k. yes the whole way up to k. go off 🔥
• --threshold <t> — compute Rips complexes up to diameter t
• --modulus <p> — compute homology with coefficients in the prime field Z/pZ 👑 (this is literally her whole thing, it's in her name)
• --ratio <r> — only show persistence pairs with death/birth ratio > r. filtering. we love a selective queen 🙈

and that's the tea, bestie 🍓 this page is from 2022-09-19, and it lives under the ripser-coeff(1) source/version tag — so like, that's the whole manual, slay, now go compute some homology 💜✨
