Consider the following arrays defined in MatLab's workspace: \begin{equation*} W = \begin{bmatrix} 1 & 0 & 0 & 0 \\ 2 & 3 & 0 & 0 \\ 4 & 5 & 6 & 0 \\ 7 & 8 & 9 & 1 \end{bmatrix} \qquad Z = \begin{bmatrix} 2 & 9 & 0 \\ 7 & 5 & 6 \end{bmatrix} \end{equation*} Retrieve the following sub-matrices from W and Z in a single line of MATLAB code: Retrieve or create from W the following sub-arrays: $\begin{bmatrix} 2\\7\\9 \end{bmatrix}$ $\begin{bmatrix} 0 & 0 & 0 & 0 & 0 & 0 \end{bmatrix}$ $\begin{bmatrix} 1 & 1 \end{bmatrix}$ Retrieve or create from Z the following sub-arrays: $\begin{bmatrix} 6 & 0 & 5 & 9 & 7 & 2 \end{bmatrix}$ $\begin{bmatrix} 6 & 5 & 7 \\ 2 & 9 & 0 \end{bmatrix}$ Retrieve or create from W and Z the following sub-arrays: $\begin{bmatrix} 9 & 0 & 2 & 3 \\ 5 & 6 & 4 & 5 \end{bmatrix}$

To retrieve the sub-array [2 7 0], we can use the following code: W([3 17 7]) To retrieve the sub-array [0 0 0 0], we can use the following code: W(8:11) To retrieve the sub-array 0, we can use the following code: W(12) To retrieve the sub-array [1 1], we can Show more…

MatLab: Let z = magic(5). a. Perform the following operations on z in the given order: i. Divide column 2 by 3. ii. Add the elements of the third row to the elements in the fifth row (the third row remains unchanged). iii. Multiply the elements of the first column by the corresponding elements of the fourth column and place the result in the first column. iv. Set the diagonal elements to 2.

[10 points] Create the following two row vectors: d=[6 -1 4 0 -2 5], and e=[7 5 9 0 1 3]. (a) Use the two vectors in a MATLAB command to create a matrix such that the first row consists of elements 1 through 3 of vector d, the second row consists of elements 2 through 4 of vector e, and the third row consists of elements 3 through 5 of vector d. (b) Use the two vectors in a MATLAB command to create a matrix such that the first column consists of elements 1 through 4 of vector d, and the second column consists of elements 2 through 5 of vector e.
(a) Create the following matrix and put the answer in p4a. Do not input element by element.
