UNTESTED CODE written in the forums interface:
function Sout = NoGUIFields(Sin)
Field = fieldname(Sin);
Data = struct2cell(Sin);
Sout = struct();
for k = 1:numel(Field)
if isa(Data{k}, 'struct')
Sout.(Field{k}) = NoGUIField(Data{k});
elseif iscell(Data{k})
Cin = Data{k};
Cout = cell(size(Cin));
for iC = 1:numel(Cin)
if isempty(regexp(class(Cin{k}), '^matlab\.(ui|graphics)\.')
Cout{iC} = Cin{iC};
end
end
Sout.(Field{k}) = Cout;
elseif isempty(regexp(class(Data{k}, '^matlab\.(ui|graphics)\.')
Sout.(Field{k}) = Sin.(Field{k});
end
end
end
This removes all fields, which matches the '^matlab\.(ui|graphics)\.' filter. Substructs are scanned recursively. You can expand this for struct arrays easily on demand. I assume there are more cases to be considered, e.g. user defined handle classes. Therefore my estimation remains: This is a dirty programming style and it will cause more troubles than it solves.
By the way: cellfun('isempty', c) is much faster than cellfun(@isempty, c).
