Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{ccc}
 -1 & -3 & 0 \\
 -3 & -1 & 2 \\
 -3 & 1 & -2 \\
 3 & 2 & 1 \\
 -2 & -2 & 2 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 -1.35 \\
 2.39 \\
 2.1 \\
 2.93 \\
 2.12 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 -0.625 \\
 1.034 \\
 1.026 \\
\end{array}
\right)$
