I have a vector: a = [1 5 7 2 6 8 9 0 2] and b=[5 8 1 0 3 6 9 8 2] (both have the same size) I want to sort vector 'a' and accordingly vector 'b'.

a = [1 5 7 2 6 8 9 0 2] ;

b = [5 8 1 0 3 6 9 8 2] ;

[a1,ind]=sort(a) for i=1:length(a1)

b1(1,i)=b(1,ind(1,i));

end

It works. But I am wondering if there is a more professional way to get ride of this "for i=1:length(a1)" loop?

Thanks in advance.

Simply

b(ind)

wow, Thanks. It is the briefest, fastest and cutest answer I've ever got!
