checking if field values in a single struct are identical

Hello,
I have a struct (S) with 13 fields. Each field has a 'density' column. I want to do an if statement which checks if all the values in the density columns are the same for each field (all 13 of them) i.e. density vals in field 1 = density vals in field 2 etc
if...(need help with this line)
disp('same altitude')
else
disp('different heights')
end
thank you

Depending on how the inputs look exactly, maybe:
FieldC = struct2cell(S);
Eq = true;
for k = 2:numel(FieldC)
if ~isequal(FieldC{k}.density, FieldC{1}.density)
Eq = false;
break;
end
end
There are shorter methods, but please explain at first exactly, what the inputs are.

density_cell = structfun(@(C) {C.density}, YourStruct);
EQ = isequal(density_cell{:});
No explicit loop needed (but structfun is arguably a hidden loop.)
