It's also possible to sort the entire structure.

To build off of gnovice's example...

% Create a structure array
s = struct('value',{1 7 4},'file',{'img1.jpg' 'img2.jpg' 'img3.jpg'});

% Sort the structure according to values in descending order
% We are only interested in the second output from the sort command

[blah, order] = sort([s(:).value],'descend');

% Save the sorted output

sortedStruct = s(order);
