Dear all,
lets say I have the value of 1e6 and 5e6. I want to add + or - 10% of this value all the time. I mean
1e6+10%
5e6-10%
1e6-10%
5e6+10%
May be it can be random. Previously I assumed like
(rand(1,11)) + 1e6;
(rand(1,11))+ 5e6;
But it just give like rand numbers of 0.1 to 0.9 but I want in percentage as mentioned abover.
Can someone reply me quickly

Homework? This might be right:
>> x = x .* (1 + 0.2*(rand(size(x))-0.5));
