I want to make vector of 20 rows and 1 column suppose this vector [1;1;1;1;2;2;2;2;2;2;3;3;4;4;4;4;4;4;5;5] please tell me a general code for this.

One way of doing it:
V1 = [1; 1; 1; 1];
for k1 = 2:5
if mod(k1,2) == 1
V1 = [V1; [1 1]'*k1];
else
V1 = [V1; ones(6,1)*k1];
end
end
The V1 vector is the result.

Or perhaps you would like a probabilistic method:
n = 20; % Length of desired vector
p = 1/4; % Probability of transition
v = cumsum([true;rand(n-1,1)<=p]);
