From GeoGebra Manual
CAS Syntax
- QRDecomposition( <Matrix> )
- Calculates the QR decomposition of the given matrix.
- {{example|1=
QRDecomposition({{1,2},{3,4}})
returns the matrices \begin{pmatrix}1/\sqrt{10}&3/5/\sqrt{10}/5\\3/\sqrt{10}&1/5/\sqrt{10}/5\end{pmatrix} and \begin{pmatrix}\sqrt{10}&7/5\sqrt{10}\\0&\sqrt{10}/5\end{pmatrix}.
Note: See also LUDecomposition command.
