Struct ChainMap 

pub struct ChainMap {
    pub source: ChainComplex,
    pub target: ChainComplex,
    pub components: Vec<Vec<Vec<i64>>>,
}

A chain map f: C_• → D_• (a degree-0 morphism of chain complexes).

Fields

source: ChainComplex

Source chain complex.

target: ChainComplex

Target chain complex.

components: Vec<Vec<Vec<i64>>>

Component matrices f_n: C_n → D_n.

Implementations

impl ChainMap

pub fn new( source: ChainComplex, target: ChainComplex, components: Vec<Vec<Vec<i64>>>, ) -> Self

Create a chain map.

pub fn induced_homology_rank(&self, n: usize) -> usize

Compute the induced map on homology H_n(C) → H_n(D) (returns rank of image).

Trait Implementations

fn clone(&self) -> ChainMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainMap

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