Write a MATLAB function called calculateFactorial that takes an integer input n and returns the factorial of n$.$

$-----------------$

Remember, a factorial function calculates the product of all positive integers less than or equal to a given positive integer n$.$ It is denoted by the symbol n$!$

Mathematically, the factorial of a non$-$negative integer n is represented as:

n$!=$n$\backslash$times $($n$1)\backslash$times $($n$2)\backslash$times $...\backslash$times $3\backslash$times $2\backslash$times $1$

For example:

$5!=5\backslash$times $4\backslash$times $3\backslash$times $2\backslash$times $1=120$

$3!=3\backslash$times $2\backslash$times $1=6$

$0!$ is defined to be $1$ by convention.
