Implementations§

Source§

impl<R, F, M> ChainFVect<R, F, M>
where R: HomSigns, F: Ring + Clone, M: EffortfulMatrixStore<F>,

Source

pub fn concentrated_in_0(dimension: usize) -> Self

a single vector space of dimension concentrated in degree 0

Source

pub fn dimensions_each_index(&self) -> Vec<(i64, usize)>

what are the dimensions of the vector spaces at each HomologicalIndexing

Source

pub fn dimensions_of_that(&self, which_index: i64) -> usize

what are the dimensions of the vector spaces at which_index specifically

Source

pub fn bettis_each_index(&self) -> Vec<(i64, usize)>

all the betti numbers

Source

pub fn shift_all(&mut self, how_much: i64)

shift the complex by how_much depending on the sign of this and the marker R of HomSigns this may be in the direction of the differential or not

Source

pub fn prepend_zero_spaces(&mut self, how_many: i64)

put more zero vector spaces before the first nonzero differential (not trivially 0, it might be 0 but not obviously) puts them opposite the direction of the differential

Source

pub fn align_together(&mut self, other: &mut Self)

get these two to line up so they start with the same HomologicalIndexing

Source

pub fn prepend_space( &mut self, new_dimension: usize, new_differential: M, ) -> Result<(), bool>

like prepend_zero_space put a vector space before the first differential (one that is not implicitly 0) but here we are putting a nontrivial vector space and a differential to the next space

§Errors

Err(false) if the dimension of the space being appended/prepended did not match the dimensions of the new_differential matrix Err(true) if d^2 \neq 0
