Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{ccc}
 -2 & 2 & -2 \\
 3 & -2 & 1 \\
 -2 & -1 & -2 \\
 1 & 2 & -3 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 2.38 \\
 -1.7 \\
 0. \\
 1.28 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 -0.209 \\
 0.628 \\
 -0.13 \\
\end{array}
\right)$
