Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{cc}
 0 & 2 \\
 1 & -2 \\
 2 & 2 \\
 -2 & 2 \\
 -1 & 0 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 0.12 \\
 -0.51 \\
 0.1 \\
 0.46 \\
 0. \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 -0.096 \\
 0.137 \\
\end{array}
\right)$
