Generate 5 random numbers, where their sum should be less/equal to 50.

while true
A=randi([1 15],5,1);
if(sum(A)<=50)
break;
end
end
disp(A)
disp(sum(A))

while true
t=15;
A=t*rand(5,1);
if(sum(A)<=50)
break;
end
end
disp(A)
disp(sum(A))
You can change t.

If the numbers are supposed to be any five positive integers, do this:
b = true;
while b
x = 50*randi(5,1);
b = sum(x)>50;
end
If the numbers can be any non-negative real numbers, change the third line above to:
x = 50*rand(5,1);
