Assume the file F$.$ m consists of the following lines:

The following MarLaB code uses the function $m-$file F$.m$ to implement Euler's method

to generate a numerical solution of an initial$-$value problem $($IVP$).$

$($a$)[1$ mark$]$ What is the time$-$step used in this computation? How many time$-$steps

are taken? Over what interval $t_{0}t{t}_{\text{f}\text{i}\text{n}\text{a}\text{l}}$ is the solution computed?
