Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{ccccc}
 -1 & 3 & -2 & -3 & 1 \\
 1 & -1 & 3 & 0 & -2 \\
 0 & 0 & -2 & 1 & -3 \\
 2 & 3 & 3 & -3 & -3 \\
 3 & 2 & 1 & -2 & -2 \\
 1 & 1 & 0 & -3 & 0 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 -0.13 \\
 0.69 \\
 -0.65 \\
 1.18 \\
 2.06 \\
 -2.43 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 0.514 \\
 1.401 \\
 0.462 \\
 1.299 \\
 0.319 \\
\end{array}
\right)$
