how to get the even numbers between 2 numbers using a loop

So, for example, between 5 and 13 it would show: [6 8 10 12]

So what have you tried so far? We tend to not do homework (or what appears to be homework whether is or not) w/o the poster showing efforts made to date and asking a specific question. Just posting a solution helps neither party...

The easy way without a loop is:

first  =  5;
second = 13;

v = first:second;
v_even = v(rem(v,2)==0)

With a loop, it’s a bit more complicated:

k2 = 1;
for k1 = first:second
    if (rem(k1,2)==0)
        v_even(k2) = k1;
        k2 = k2 + 1;
    end
end

>> A = 5;
>> Z = 13;
>> A+rem(A,2):2:Z
ans =
   6     8    10    12

This method generates a vector containing only the even numbers, which is much more efficient than generating a vector with all values and then keeping only the even values.

k2 = 1;

for k1 = first:second

if (rem(k1,2)==0)

v_even(k2) = k1;

k2 = k2 + 1;

end

end
