Create an evenly$-$spaced row vector A with elements starting at $0$ and ending at $50$ with increments of $0\mathrm{.}5.$

Create a row vector B with $80$ evenly$-$spaced elements starting at $0$ and ending at $\frac{}{2}.$

Create a row vector $C$ that is an unsigned $8-$bit integer data type with elements counting backward from $200$ to $0$ in increments of $5.$
