Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{ccc}
 2 & -2 & 2 \\
 1 & 2 & 3 \\
 -2 & 0 & 3 \\
 3 & -3 & 1 \\
 1 & -1 & -2 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 -2.19 \\
 0.48 \\
 2.35 \\
 2.97 \\
 2.96 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 -0.115 \\
 -0.443 \\
 0.068 \\
\end{array}
\right)$
