Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{cc}
 3 & -1 \\
 -1 & -2 \\
 1 & 1 \\
 -3 & -2 \\
 3 & 0 \\
 2 & -3 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 -0.9 \\
 -2.31 \\
 2.17 \\
 1.3 \\
 -0.01 \\
 -2.84 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 -0.237 \\
 0.716 \\
\end{array}
\right)$
