MATLAB: Help determining values of a vector

functionindexingMATLABmodulus

Hello, I am writing a code that asks the user to input a number a values then takes those values and puts them into an array. Then evaluates each element of the array to determine if it is pos, neg, even, or odd. Here's what I have
function [Poseven]= Vect(UserNum);
    str = inputdlg('Enter 10 numbers seperated by spaces or commas');
      UserNum = str2num(str{1});
      if mod(UserNum, 2) == 0, UserNum > 0; 
         Poseven = UserNum(1,1:end)
      end
 end
The only thing I am not understanding is why or how rather to display the numbers of the original vector where the modulus value is zero and greater than zero.

Your lines
      if mod(UserNum, 2) == 0, UserNum > 0; 
         Poseven = UserNum(1,1:end)
      end
are the same as
      if mod(UserNum, 2) == 0
         UserNum > 0; 
         Poseven = UserNum(1,1:end)
      end
which calculates whether UserNum > 0 and then throws away the result of the comparison. If you want to combine conditions, you need to use one of &&, ||, &, or |
Note: you probably want to use either a loop or logical indexing.
