$2$ Prime factorization

Write a function to find the prime factors of an input number, not $0.$ The function

should take an integer and output a vector whose entries are the prime factors of the

input. These entries can be repeated ie$.$ if you multiply all the entries you should get the

original number. If the input equals to $0,$ print an error and output the empty vector $[$

$].$ If the input equals to $1,$ output just the number $1.$ Do not use the Matlab function

factor$()$ to solve this problem.

Then in the main script, test the function with the following inputs: $256,79,1000,3.$

Hint: You may want to reuse the function is$\_$prime from Oct $7$ notes to help determine

the output for prime numbers. If you decide to use it$,$ make sure to make a function file

for is$\_$prime and include it with your folder and submission $($this will increase the total

of files to be submitted to $5$: $4$ function files and $1$ main script$).$
