Sort a vector according to another vector

Hi

I have tow vectors A and B:

 A = [4 8 5 9 1]
 B = [3 5 4 2 1]

If I sort A with B like this:

 C = A(B)

I will get:

 C = [5 1 9 8 4]

But I want C like this:

 C = [1 9 4 5 8]

How can I do that?

Thank you, M. Rajaei

[~,Bsort]=sort(B); %Get the order of B
C=A(Bsort)

C =

     1     9     4     5     8

OK. Thank you so much. I got it.

how can you do the same thing with n x 2 array?

I do it like this

vectors = [3 4;5 12];
modules = [5;13];
[~,modulesSort] = sort(modules); %Get the order of B
%C=A(modulesSort); %not works
% do this
vectorsSortedByModule = vectors(modulesSort,:);
