Q$9$: Tiling vectors.

Let $u$ be the first column of the structured matrix $K$ indicated below:

$K=\left[\begin{array}{cccc}1& 3& \text{c}\text{d}\text{o}\text{t}\text{s}& 28\\ 31& 34& \text{c}\text{d}\text{o}\text{t}\text{s}& 58\\ \text{v}\text{d}\text{o}\text{t}\text{s}& \text{c}\text{d}\text{o}\text{t}\text{s}& \text{c}\text{d}\text{o}\text{t}\text{s}& \text{v}\text{d}\text{o}\text{t}\text{s}\\ 91& 94& \text{c}\text{d}\text{o}\text{t}\text{s}& 118\end{array}\right].$

Edit the loop below so that it generates the matrix $K$ by appending suitable column vectors.

$\%$Edit the lines below to generate the matrix $K$ described above.

$u=1$;

$K=[]$;

for $k=1$:$1$

$K=\left[\begin{array}{cc}K& u\end{array}\right]$;

end
