How to pick values in a matrix due to values in another matrix

Hi,

I have two data sets (f and g) with 5 values in each and by using the tiedrank command I have ranked the lowest to the highest value in data set g. What I want to to is pick values in f that correspond to the ranked values in d. So I want to find where the value is 1,2, and so on in d and sample the value at the same index in matrix f. These values will be sampled in f_marked. Is there an easy way to do this in matlab?

clc; clear all; close all;

f = [1 5 9 8 2];
g = [2 4 1 5 7];
d = tiedrank(g);
d = [2 3 1 4 5];
f_marked = [9 1 5 8 2];  % my new sorted vector of f based on d

[~, order] = sort(d);
f_marked = f(order);

Another option:

f_marked = accumarray(d', f)'

This don't work. When I put f_marked = f(d) I get [5 9 1 8 2]. I should get [9 1 5 8 2]...

Indeed. I wasn't thinking clearly when I wrote my reply.

Edited answer that does give the correct result

The simplest answer is to use d and f directly:

>> x(d) = f
x =
   9     1     5     8     2

Indeed. I've got a cloudy mind today. Time to go home...
