$[$arrays$]$ Use arrays and array manipulation methods to satisfy the below requirements.

$($a$)(9$ points$)$ Create the following matrix using diag function,

$A=\left[\begin{array}{cccccc}2\mathrm{.}29({10}^3)& 5\mathrm{.}8& 0& 0& 0& 0\\ 5\mathrm{.}8& 2\mathrm{.}29({10}^3)& 5\mathrm{.}8& 0& 0& 0\\ 0& 5\mathrm{.}8& 2\mathrm{.}29({10}^3)& 5\mathrm{.}8& 0& 0\\ 0& 0& 5\mathrm{.}8& 2\mathrm{.}29({10}^3)& 5\mathrm{.}8& 0\\ 0& 0& 0& 5\mathrm{.}8& 2\mathrm{.}29({10}^3)& 5\mathrm{.}8\\ 0& 0& 0& 0& 5\mathrm{.}8& 2\mathrm{.}29({10}^3)\end{array}\right]$

Usage of diag:

$--$ M $=$ diag $($V$,$ K$)$

Return a diagonal matrix with vector V on diagonal K $.$

The second argument is optional. If it is positive, the vector is placed on the K$-$th superdiagonal. If it is negative, it is placed on the $-$ K $-$th subdiagonal. The default value of K is $0,$ and the vector is placed on the main diagonal. For example:

diag $([1,2,3],1)$

$=>\{\begin{array}{ccc}\text{:}[0,& 1,0,& 0]\end{array}$

$0,020$

$0,0,0,3$

$0000$

Fill in the blanks in the answer:

$($b$)(6$pt points$)$ Delete the first, third, and fourth rows of the matrix in $($a$).$ Fill in the blanks in the answer:

$($c$)(4$pt points$)$ Insert a row of ones as the first row of the matrix in part $($a$)$:

Fill in the blanks in the answer:

$1A=[$ ; A$]$;

$($d$)(6$ points$)$ Take the lower right $33$ matrix from the matrix in $($a$)$ and assign the extracted matrix to a new matrix called $B.$

Fill in the blanks in the answer:

$1B=ACq,$
