What you have tried so far?
dec2bin(1:15)
Using for loop, please share your efforts?

>> dec2bin(0:2^4-1)-'0'
ans =
0 0 0 0
0 0 0 1
0 0 1 0
0 0 1 1
0 1 0 0
0 1 0 1
0 1 1 0
0 1 1 1
1 0 0 0
1 0 0 1
1 0 1 0

I think it is not very efficient, but works
a = dec2bin(0:15);
i = 1;
while i<17
c = randi([0 1],1,4);
if(a(i,1:4) == sprintf('%g',c))
b(i,1:4) = c;
i = i+1;
end
end
b =
0 0 0 0
0 0 0 1
0 0 1 0
0 0 1 1
0 1 0 0
0 1 0 1
0 1 1 0
0 1 1 1
1 0 0 0
1 0 0 1
1 0 1 0
1 0 1 1
1 1 0 0
1 1 0 1
1 1 1 0
1 1 1 1
