# full(::LinAlg.QRCompactWYQ, ?)

```
.. full(QRCompactWYQ[, thin=true]) -> Matrix
Converts an orthogonal or unitary matrix stored as a ``QRCompactWYQ``
object, i.e. in the compact WY format [Bischof1987]_, to a dense matrix.
Optionally takes a ``thin`` Boolean argument, which if ``true`` omits the
columns that span the rows of ``R`` in the QR factorization that are zero.
The resulting matrix is the ``Q`` in a thin QR factorization (sometimes
called the reduced QR factorization). If ``false``, returns a ``Q`` that
spans all rows of ``R`` in its corresponding QR factorization.
