Problem:
Find the least squares vector given the matrix
$\left(
\begin{array}{cc}
 2 & -3 \\
 -3 & 3 \\
 -1 & 1 \\
 3 & -1 \\
 1 & -1 \\
\end{array}
\right)$ and the vector
$\left(
\begin{array}{c}
 -0.16 \\
 0.1 \\
 0.18 \\
 1.4 \\
 0.83 \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 0.61 \\
