One thing you could do is the following:
A = (ceil(499.5+100*rand(10000,7)));
indicesOf4000 = find(sum(A,2)==4000);
Then, you could see the set of numbers by:
for k = 1:length(indicesOf4000)
disp(num2str(A(indicesOf4000,:)))
end
If indicesOf4000 seems to be blank, you could either run A = ... again, or you could increase the number of sample sets from 10000 to a higher value.
Best.
