Struct PermutationView 

pub struct PermutationView {
    pub perm: Vec<usize>,
}

A permutation matrix view: row i has its one in column perm[i].

Fields

perm: Vec<usize>

perm[i] is the column holding the one in row i.

Implementations

impl PermutationView

pub fn matvec<S: Semiring>(&self, v: &[S]) -> Result<Vec<S>, AlgebraError>

Apply to a vector: result[i] = v[perm[i]].

pub fn materialize<S: Semiring>( &self, limits: AlgebraLimits, ) -> Result<Matrix<S>, AlgebraError>

Materialize as a dense permutation matrix, guarded by limits.
