Hi,
I have seen that a cell array element can be a structure. (See:
http://www.octave.org/octave-lists/archive/octave-maintainers.2002/msg00012.html)

The example given is:
octave:1> X{2,2}.bar(2).foo(2:3,2:3) = rand(2)

But I get the following error message when I try this statement:
error: matrix cannot be indexed with .
error: assignment failed, or no method for `<unknown type> = matrix'
error: evaluating assignment expression near line 1, column 28
octave:1> 

I have tried this on versions 2.1.44 and 2.1.50. I don't even need
structure arrays. It would be sufficient if I could assign X{2,2}.a = 1. 

Is there a patch? I also wish to load and save cell arrays with structures.
If need be, I would consider contributing code to get this to work.

Thanks!
Paul Griffiths
