MATLAB: Help me with the function of odd or even!

Question

Hi! I need help with my function. When I put a negative number, matlab gives me an error;

Error using disp
Too many output arguments

This function is about that the user put any number and the function returns a 1 if it is even, a 0 if it is odd or if the number is not a integer an error message. Thanks a lot.

function[v]=dimesiespar2(n)
 if  rem(n,1) == 0 && n>0
     if rem(n, 2)==0
         v=1;
     else
         v=0;
     end
 else 
     v= disp('el número entrado no es un entero positivo'); 
 end

Answer 1

       v = 'el número entrado no es un entero positivo';
