Expand description
Computes the inverse of a matrix, given its QR decomposition with column pivoting,
and stores the result in qr_factors
.
§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
col_perm
doesn’t have the same dimension asqr_factors
. - Panics if the provided memory in
stack
is insufficient (seeinvert_in_place_req
).
