How to create an array with first 100 elements as 1, next 100 as 2 and so on?

I want to create an array which looks like this:

[1 1 1 1 ...(100 time), 2 2 2 2...(100 times), 3 3 3 3....]

like this.

I'm very new to matlab, Any help?

repelem()

[Sahil Islam]

Can you give a proper code. Like repelem() does that. But how to make one array of all those?

n = 5;
A=[];
for i = 1 : 5
    A=vertcat(A,i*ones(1,100));
end
disp(A)

You can change vertcat to horzcat if you want all in one row.
