Function invert

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

Expand description

Computes the inverse of a matrix, given its partial pivoting LU decomposition, and stores the result in dst.

§Panics

Panics if the LU factors are not a square matrix.
Panics if the row permutation doesn’t have the same dimension as the matrix.
Panics if the destination shape doesn’t match the shape of the matrix.
Panics if the provided memory in stack is insufficient (see invert_req).
