Is your question "How to check if a variable consists of even numbers?"
Google "even number mod matlab"

If you just want to check if a variable X is an even number, then just check the value of mod(x,2). If the result is zero, then X was even.
X = randi(10,1,5)
X =
4 10 8 9 7
mod(X,2)
ans =
0 0 0 1 1
So the first three elements of X were even numbers, because the modulus base 2 were zero for those elements. Here, zero tell you even. 1 tells you odd. If you want a result that is true for even numbers, then do something like this:
mod(X,2) == 0
ans =
1×5 logical array
1 1 1 0 0
As you can see, the result is now true for the even numbers.
If you want to see if all, or any of them were even, then do one of these as appropriate:
all(mod(X,2) == 0)
ans =
logical
0
any(mod(X,2) == 0)
ans =
logical
1
So they were not all even, but SOME of them were even.
