a_{11} = \frac{1}{2} ∣ - 2 ∣ = 1; a_{12} = \frac{1}{2} ∣ 1 - 6 ∣ = \frac{5}{2}

a_{21} = \frac{1}{2} ∣ 2 - 3 ∣ = \frac{1}{2}; a_{22} = \frac{1}{2} ∣ 2 - 6 ∣ = 2

a_{31} = \frac{1}{2} ∣ 3 - 3 ∣ = 0; a_{32} = \frac{1}{2} ∣ 3 - 6 ∣ = \frac{3}{2}

\Rightarrow M = [\begin{array}{cc} 1 & 5 / 2 \\ 1 / 2 & 2 \\ 0 & 3 / 2 \end{array}]
