Expand description

Result of sparse QR factorization.

Stores the factorization in implicit Householder form:

Householder vectors v_k and scalars tau_k define Q = I - V * T * V^T
R is stored as a dense upper triangular matrix
Column permutation for pivoted QR

Fields§

§householder_v: Vec<Vec<F>>

Householder vectors, stored column-wise. householder_v[k] is the k-th Householder vector (length m).

§tau: Vec<F>

Householder scalars tau[k] = 2 / (v^T v).

§r_data: Vec<Vec<F>>

R factor stored as dense row-major (min(m,n) x n).

§col_perm: Vec<usize>

Column permutation (P): r_data columns correspond to original columns col_perm[j].

§m: usize

Number of rows (m).

§n: usize

Number of columns (n).

§rank: usize

Numerical rank determined during factorization.
