Function extendr_api::prelude::modules::cholesky::llt::reconstruct::reconstruct_lower

E: ComplexField,
Expand description
Computes the lower triangular part of the reconstructed matrix, given its Cholesky
decomposition, and stores the result in dst
.
§Panics
- Panics if
cholesky_factor
is not a square matrix. - Panics if the destination shape doesn’t match the shape of the matrix.
This can also panic if the provided memory in stack
is insufficient (see
reconstruct_lower_req
).
