try repmat function:
A=[30 2 4 6 8 10];
no_of_rows=1;
no_of_repeated_times=3;
B=repmat(A,no_of_rows,no_of_repeated_times)
B = 1×18
30 2 4 6 8 10 30 2 4 6 8 10 30 2 4 6 8 10

I guess you are talking about xtick
A=[30 2 4 6 8 10];
no_of_rows=1;
no_of_repeated_times=3;
B=repmat(A,no_of_rows,no_of_repeated_times);
% plot anything
x = 0:5:50*pi;
y = sin(x);
plot(x,y)
xticklabels(B)

I think this is what you are asking for. Note that this isn't going to be very pretty if you have more than a couple of months to plot. And, of course, it doesn't account for varying numbers of days in a month.
plot(1:60)
xticks(1:2:60)
xticklabels(repmat([30 2:2:28], 1, 2))
