<SNIP structure field arithmetic...

one of the many solutions

% create some data
     s1.a=1:5;
     s1.b=1:5;
     s2.a=11:15;
     s2.b=101:105;
     fun=@plus; % select your element-by-element function
% the engine
     fn=fieldnames(s1);
     fh=@(sa,sb,fd,fun) fun(sa.(fd),sb.(fd));
     r=cellfun(@(x) fh(s1,s2,x,fun),fn,'uni',false);
     r=cell2struct(r,fn);
% the result
     s1
     s2
     r
