Expand description
Given the QR factors of a matrix $A$ and a matrix $B$ stored in rhs
, this function computes
the solution of the linear system:
$$\text{Op}_A(A)^\top X = B.$$
$\text{Op}_A$ 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
qr_factors
is not a square matrix. - Panics if the number of columns of
householder_factor
isn’t the same as the minimum of the number of rows and the number of columns ofqr_factors
. - Panics if the block size is zero.
- Panics if
rhs
doesn’t have the same number of rows as the dimension ofqr_factors
. - Panics if the provided memory in
stack
is insufficient (seesolve_transpose_in_place_req
).
