Hi Octave users

I have the a structure

a.data.d1
a.data.d2
a.data.d3
a.data.d4
...

I want to write a function caltulatetes somthing out of the datasets
and stores in new structure

a.result.d1
a.result.d2
a.result.d3
a.result.d4
...

function diff_first_struct(struct)
  for [matrix,key] = struct.data
    struct.result.key = diff_first(matrix);  
  endfor
endfunction

But there are two problems. That would need call by reference and a
operator that makes it possible to defines the name
struct1.result.key by avaluating key like struct.result.$(key), or
something like that.

what possibilities do you see expect

a.result.d1 = func(a.data.d1);
a.result.d2 = func(a.data.d2);
a.result.d3 = func(a.data.d3);
a.result.d4 = func(a.data.d4);

Thanks Hendrik Naumann
