\subsection{Problem 12}
|
|
|
|
Compute the QR factorization of the matrix:
|
|
|
|
\begin{equation*}
|
|
\matr{A} =
|
|
\begin{bmatrix}
|
|
0 & -1 & -3 \\
|
|
0 & \phantom{-}0 & -2 \\
|
|
0 & -2 & -1
|
|
\end{bmatrix}
|
|
\end{equation*}
|
|
|
|
How many flops (multiplications/divisions, additions/subtractions) are needed to perform the QR factorization with the Householder transformations and Givens rotations? |
