Essay

The following matrices have already been defined in MATLAB: $$A = \left[ \begin{array} { c c c c } 2 & 4 & 10 & 13 \\16 & 3 & 7 & 18 \\8 & 4 & 9 & 25 \\3 & 12 & 15 & 17\end{array} \right] \quad B = \left[ \begin{array} { c c c c } - 1 & 3 & - 5 & 10 \\6 & 13 & 11 & - 5 \\- 3 & 12 & 0 & 2 \\2 & 12 & - 5 & 8\end{array} \right]$$
What would be the outputs of the following MATLAB inputs:
- $$\gg \mathrm { B } ( : , 3 : 4 )$$
