Sort a vector according to another vector
显示 更早的评论
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

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,:);
