Problem $2$

Generate a $3$x$4$ matrix $($called A$)$ of random real $($floating$-$point$)$ numbers, each in the range $(7\mathrm{.}5,32\mathrm{.}6)$; Replace the second row with $2\mathrm{.}5$:$0\mathrm{.}5$:$4\mathrm{.}0.$ Replace the first column $($you decide with which values$).$

Generate a $3$x$5$ matrix $($called B$)$ of random integers, each in the inclusive range from $-10$ to $10.$ Generate a $4$x$4$ matrix $($called C$)$ of random integers, each in the inclusive range from $-8$ to $16.$

If you can do the calculation of A$.*$B$,$ please show the answer. If not, please explain why.

If you can do the calculation of A$*$C$,$ please show the answer. If not, please explain why.

Refer the second column of A and store in a variable vec.

What is the result of B$.^2?$

Can the operation C$*$C be performed? If so$,$ show the answer. If not, explain why

Delete the last row of C$.$

Delete the last column of C$.$
