I need to order a list that is dependant on another list. how to change both lists?

Question

I have a Matlab program that generates a list x = 6.1692 8.1863 5.8092 8.2754 6.0891 the program also outputs another list aspl = 680 637 669 599 69

Answer 1

Use the second output of sort:

%# sort aspl, get new order of aspl
[sortedAspl, sortOrder] = sort(aspl);
%# reorder x the same way as aspl
sortedX = x(sortOrder);
