How to sort a structure array

问题

How do I sort the oo structure array alphabetical order by item name.

oo = struct('Item', {'Quill','Ink Pen', 'Pencil'}, 'Cost', {10, 2, 1})

I tried using the sort() function but it didn't work?
Thank you.

First index your field, in this case oo.Items which returns a comma separated list. For string data use {} to concatenate to a cell of strings, otherwise use [] to get an array:

%get the right order using second output of sort
[~,index]=sort({oo.Item})
%sort it
oo=oo(index)
