$1\mathrm{.}97$ A rectangular pulse $x(t)$ is defined by

$x(t)=\{\begin{array}{cc}10,& 0t5\\ [0,& \text{o}\text{t}\text{h}\text{e}\text{r}\text{w}\text{i}\text{s}\text{e}& ].\end{array}$

Generate $x(t),$ using

$($a$)$ A pair of time$-$shifted step functions.

$($b$)$ An M$-$file.Create a MATLAB code for the problem since this is a MATLAB problem.
