Struct CWComplex 

pub struct CWComplex {
    pub cells: Vec<usize>,
    pub attaching_degrees: Vec<Vec<i32>>,
}

Cellular homology computation via CW structure.

Fields

cells: Vec<usize>

Number of n-cells: cells[n] = count of n-cells.

attaching_degrees: Vec<Vec<i32>>

Attaching map degrees: degrees[n][i] = degree of i-th attaching map in dimension n+1.

Implementations

impl CWComplex

pub fn new(cells: Vec<usize>) -> Self

pub fn euler_characteristic(&self) -> i64

Euler characteristic from cell counts: χ = Σ (-1)^k |cells_k|.

pub fn betti_upper_bound(&self) -> Vec<usize>

Tight Betti bound: β_k <= cells[k].

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CWComplex

fn fmt(&self, f: &mut Formatter<'_>) -> Result
