Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{ccccc}
 -2 & -3 & 0 & 1 & -3 \\
 -1 & -2 & -2 & 2 & -3 \\
 -1 & 3 & 1 & 2 & 2 \\
 1 & -3 & 1 & 0 & -3 \\
 2 & 1 & -3 & -3 & 2 \\
 -3 & -1 & 3 & -2 & 3 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 1.66 \\
 0.92 \\
 1.79 \\
 2.03 \\
 -0.52 \\
 -1.14 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 0.392 \\
 -0.558 \\
 0.016 \\
 0.83 \\
 0.36 \\
\end{array}
\right)$
