Function reconstruct_in_place

pub fn reconstruct_in_place<I, E>(
    lu_factors: MatMut<'_, E>,
    row_perm: PermRef<'_, I>,
    parallelism: Parallelism<'_>,
    stack: PodStack<'_>,
)where
    I: Index,
    E: ComplexField,

Expand description

Computes the reconstructed matrix, given its partial pivoting LU decomposition, and stores the result in lu_factors.

§Panics

Panics if the row permutation doesn’t have the same dimension as the number of rows of the matrix.
Panics if the provided memory in stack is insufficient (see reconstruct_in_place_req).
