A good option is to use the try catch statement, then:
prompt = {'Choose the figure name','Choose the Tree name',...
'Choose the Clusters name','Choose the Roots name'};
answer=inputdlg(prompt);
try
if ~isempty(answer{1})
assignin('base',answer{1},app.Figure);
end
if ~isempty(answer{2})
assignin('base',answer{2},app.Tree);
end
if ~isempty(answer{3})
assignin('base',answer{3},app.Clusters);
end
if ~isempty(answer{4})
assignin('base',answer{4},app.Roots);
end
catch
%Some things to do if answer is not complete
end
