MATLAB: My professor assigned me to do the this homework with two numbers and writing a code that find which one is the prime for these two numbers

the code that giving in the problem is for one number only not for two

Write a user-defined function that determines if a number is a prime number. Name the function pr=Trueprime(m), where the input arguments m is a positive integer and the output argument pr is 1 if m is a prime number and 0 if m is not a prime number. Do not use MATLAB’s built-in functions primes and isprime. If a negative number or a number that is not an integer is entered when the function is called, the error message “The input argument must be a positive integer.” is displayed.
(a) Use the function with 733, 2001, and 107.5
%%This is for one number
function pr=Trueprime(m)
if floor(m)~=m
    disp('number is not a whole number')
else
 for i=2:1:(m-1)
     if rem(m,i)==0
         disp('Number is not prime')
         break
     end
     if i==(m-1)
         disp('Number is prime')
     end
 end
end

Best Answer

So what is the problem? The only obvious issue I see is that it doesn't check if the number is negative:
function pr=Trueprime(m) 
if floor(m)~=m | m<=0
    disp('The input must be a positive integer')
else
    for i=2:1:(m-1) 
        if rem(m,i)==0 
            disp('Number is not prime') 
            break 
        end
        if i==(m-1) 
            disp('Number is prime') 
        end
    end
end
