reduce-simplicial-complex

Given an oriented simplicial complex, this module computes a minimal basis for the complex in the integer homology sense. That is, it cancels out all pairs of equivalent cells which have opposite orientation.

Example

var reduceCells = require('reduce-simplicial-complex')

var cells = [
  [1, 2, 3],
  [2, 1, 3],
  [3, 2, 1],
  [4, 5, 6],
  [7, 8]
]

console.log(reduceCells(cells))

Install

npm i reduce-simplicial-complex

API

require('reduce-simplicial-complex')(cells)

Cancels all pairs of oppositely oriented cells

• cells is an array of cells

Returns A collapsed list of cells

Note This is done in place. If you need a copy, you should make a copy first, for example using cells.slice().
