I want to generate a matrix of size
(1500x1)
in which first 100 rows should be having the value of 1, next 200 rows should be having the value of 1 and 2 arranged randomly, next 300 should be having the value of 1,2 and 3 arranged randomly, next 400 rows should be having the value of 1,2,3 and 4 arranged randomly and next 500 rows should be having the value of 1,2,3, 4 and 5 arranged randomly.
Could anyone please help me on this.

hi=repelem((1:5)',100*(1:5));
r=ceil(rand(size(hi)).*hi)

This should do it.
m1 = ones([100,1]);
m2 = randi([1 2],200,1);
m3 = randi([1 3],300,1);
m4 = randi([1 4],400,1);
m5 = randi([1 5],500,1);
Ans = [m1 ; m2;m3;m4;m5];

Ran in:
data=cell(5,1);
for n=1:numel(data)
data{n}=randi([1 n],n*100,1);
end
data=cell2mat(data);
size(data)
ans = 1×2
1500 1
