Struct ModuleMatrix 

pub struct ModuleMatrix {
    pub rows: usize,
    pub cols: usize,
    pub entries_ntt: Vec<NttPoly>,
}

Public matrix A stored row-major as NTT polynomials Â_{i,j}.

Fields

rows: usize

Number of rows k.

cols: usize

Number of columns l.

entries_ntt: Vec<NttPoly>

Row-major k · l entries.

Implementations

impl ModuleMatrix

pub fn expand_from_seed(seed: &[u8; 32], rows: usize, cols: usize) -> Self

Expand A from seed ρ with crate::expand_a_from_seed.

pub fn mul_vec_ntt(&self, v_ntt: &[NttPoly]) -> ModuleVec

y_i = InvNTT( Σ_j Â_{i,j} ∘ v̂_j ) — same pattern as ML-DSA compute_matrix_x_mask.

pub fn mul_vec(&self, v: &ModuleVec) -> ModuleVec

ModuleMatrix::mul_vec_ntt with automatic NTT on each input Poly.
