Task $2$: Two prime number$-$related functions

a$)$ Write your own MATLAB $($or Octave$)$ function to check if a number is a prime.

Your function shall take a natural number as an input and return a boolean value to

indicate if the input number is prime $($return value true$)$ or not $($return value false$).$

b$)$ Write a MATLAB $($or Octave$)$ function which takes a number n as an input parameter

and returns a vector which contains the rst n prime numbers.

You are only allowed to use basic arithmetics $($addition$,$ subtraction, multiplication,

division, modulo$)$ together with if$/$else$-$branching, for$-$loops and while$-$loops for this

part of the project.
