Generating Array from nested loops

So Ive been trying to create an array of 4 numbers using nested loops The first number goes from 1:5 The second number goes from 1:2 The third number goes from 1:3 The fourth number goes from 1:4

so that

A= [1 1 1 1 
    1 2 1 1 
    1 2 2 1 
    1 2 2 2  
    1 3 1 1 
    1 3 2 1 
    . . . . 
    . . . . 
    5 2 3 4 ]

So i been trying to use nested loops to generate that example

for n1 = 1: 5 
    n(n1,:) = [n1]
    for n2 = 1: 2
        n(n2,:) = [n2]
    end 
 end

But this replaces my previous input. How do i make so i make that 4 element array of all possible values.

Download combinations or allcomb from MATLAB FEX:

>> sortrows(combinations(1:5,1:2,1:3,1:4))
ans =
