Chapter 2, Problem 41P

The following matrix is defined in MATLAB:

S=

1 2 3 4 5 6

7 8 9 10 11 12

13 14 15 16 17 18

19 20 21 22 23 24

By hand (pencil and paper) write what will be displayed if the following commands are executed by MATLAB. Check your answers by executing the commands with MATLAB.

(a) $\text{A}=\text{S}(\text{2},\left[\text{2},\text{4}\right])$(b) $\text{B}=\text{S}\left(\text{3},\left[\text{3}:\text{5}\right]\right)$

(c) $\text{C}=\text{S}\left(\left[\text{2}:\text{4}\right],\left(\text{4}:\text{6}\right]\right)$ (d) $\text{D}=\text{S}(:,\left[\text{1}:\text{3}\right])$
