Rearranging a Vector Back Again

Hello,

I have a vector x:

x =

0 0 1 1 0 1 0 0 1 1

I want arranged having zeros first then ones, so I used this: [x,indices]=sort(x,2)

x =

0 0 0 0 0 1 1 1 1 1

indices =

1 2 5 7 8 3 4 6 9 10

The indices vector is for me to know where each number was displaced from its orignial position to, however, after I finished using the modified x, I would like to rearrange it as its old form again using indices vector, how can I do that?

I used this but it didn't work: sort(indices); x=x(indices)

x =

0 0 0 1 1 0 0 1 1 1

% Original x 
x = [0 0 1 1 0 1 0 0 1 1];

% Sorted x
[x_sorted,indices]=sort(x,2);

% Original x recovered from the sorted one
x_redux(indices) = x_sorted

I renamed the variables so that you would not get confused by which x was which.
