Expand description
Given the LU factors of a matrix $A$ and a matrix $B$ stored in rhs
, this function computes
the solution of the linear system:
$$\text{Op}_A(A)X = B.$$
$\text{Op}_A$ is either the identity or the conjugation depending on the value of conj_lhs
.
The solution of the linear system is stored in rhs
.
§Panics
- Panics if
lu_factors
is not a square matrix. - Panics if
row_perm
doesn’t have the same dimension aslu_factors
. - Panics if
rhs
doesn’t have the same number of rows as the dimension oflu_factors
. - Panics if the provided memory in
stack
is insufficient (seesolve_in_place_req
).
