Replacing 2 elements with each other randomly?
显示 更早的评论
Like : a=[2 4 5 242 24] ------> a'=[2 242 5 4 24]
my code is :
rndm= myset(randperm(length(myset),2))
neighbor=myset;
dummy=myset(rndm(1));
neighbor(rndm(1))= myset(rndm(2));
neighbor(rndm(2))=dummy
It is working but sometimes i get out of bounds error. Because the myset vector includes elements like 234. If big numbers elements (like 242) have chosen by randomly then rndm(1) will be equal to 242. So myset(242) is out of bounds for sure.

a = [2 4 5 242 24];
r = randperm(length(a));
b = a;
b([r(1) r(2)]) = a([r(2) r(1)]);

I didn't look at your solution carefully, but it looks like the only essential difference is that you did
rndm = myset(randperm(length(myset),2))
where you should have done just
rndm = randperm(length(myset),2)
