Sort the fields in a struct based on value

Question

Say I have a struct:

MyStruct.a = 12;
MyStruct.b = 22;
MyStruct.c = 32;

Can I modify it so that the fields are ordered based on their value:

Answer 1

% Define initial structure:

myStruct.a = 12;
myStruct.b = 22;
myStruct.c = 32;

% Find desired order of values, rather than fieldnames:

[ ~,sortIdx ] = sort( structfun( @(x) x, myStruct ), 'descend' );

% Apply orderfields():

mySortedStruct = orderfields( myStruct, sortIdx )
