Hello,
I can’t develop the following simple model with Simulink, so please help me with it.
A generator creates a series of integers. A dedicated block shall take out the first 2 elements out of every 5 elements. For example:
Generator: [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ...] Output of this block: [1 2 6 7 11 12 ...]
Is it possible at all? Should sample time be adapted?

Try this:
m = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15]
m2 = [m(1:5:end); m(2:5:end)]
output = m2(:)'
Results in command window:
m =
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
m2 =
1 6 11
2 7 12
output =
1 2 6 7 11 12

What about with Simulink?

I don't have Simulink. I thought Simulink blocks could use MATLAB code? If not, ignore my answer.

I think such a task is easy for Matlab because in Matlab all the elements are already there before procession. In Simulink the generation and the procession are at the same time. This is the difficulty for me.
