Problem $1\mathrm{.}4$

There are several different ways to generate the following matrix in the MATLAB command line. Generate the matrix twice using at least $2$ different methods. HINT $1$: How could you use the colon operator or linspace? HINT $2$: Do the numbers follow a pattern in the rows or columns of the matrix?

$A=\left[\begin{array}{ccc}6& -10& 0\\ 4& -5& 3\mathrm{.}5\\ 2& 0& 7\end{array}\right]$

Problem $1\mathrm{.}5$

Using the A matrix you created in Problem $1\mathrm{.}4,$ display the following information to the screen.

The third column of $A$

The element in the third row and second column of $A$

The first row of $A$

HINT: Use the MATLAB code below to display the element in the first row and second column of A:

$A(1,2)$
