pub fn reconstruct<I, E>(

Expand description
Computes the reconstructed matrix, given its QR decomposition, and stores the
result in dst
.
§Panics
- 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
dst
doesn’t have the same shape asqr_factors
. - Panics if the provided memory in
stack
is insufficient (seereconstruct_req
).
