Write a Matlab function, called testprime, that takes one input argument and uses a for$-$loop and rem function to check whether its argument is a prime number. testprime$($x$)$ should return $1$ if x is a prime number and $0$ otherwise.

Your testprime function must behave as shown below:

$>>$ help testprime

testprime checks if its argument is a prime

testprime$($x$)$ is $1$ if x is a prime, $0$ otherwise.

Author:

$>>$ testprime$(12)$

logical

$0$

$>>$ testprime$(7)$

$1$

$>>$

Hint: To get a logical $1$ and logical $0$ as output of your function, see $$help true$$ and $$help false$$
