Using the function linspace$(),$ generate a row vector v$1$ with seven elements which uniformly cover the interval between $0$ and $1.$ Now generate a vector v$2$ which also covers the interval between $0$ and $1,$ but with a fixed discretization of $0\mathrm{.}1.$ Use either the function length$()$ or size$()$ to determine how many elements the vector v$2$ has. What is the value of the third element of vector v$2?$
