Here is a very simple line of code:

x = 3;
A = 1:x;
for i = 1:length(A)
    y = repelem(A(:,i),i);
    Y = y(1,:)
end

I want to generate result in the form

[1 2 2 3 3 3]

What I am doing mistake, please help me in this regard. Thanks

x = 3;

A = 1:x;

Y = [];

for i = 1:length(A)

y = repelem(A(:,i),i);

Y(length(Y)+1:length(Y)+1 +length(y)-1) = y(1,:)

end

>> A = 1:3;
>> repelem(A,1,A)
ans =
     1     2     2     3     3     3
