Get values from complex struct

Hi all,

I have a complex set of structures, where I want to extract values from:

A: 1x1000 struct

sub-struct: B: 1x1 struct

sub-struct C: 1x3 struct

I want to search the A.B.C structures for var_a = x

var_a is part of C, but it does not exist in all C.

I tried "find", but I get "Reference to non-existent field 'C'."

Cheers

"I want to search the A.B.C structures for var_a = x" - this is not clear yet.

"I tried "find", but I get "Reference to non-existent field 'C'."" - post the code and a copy of the complete error message. This allows for understanding the problem better than a vague paraphrasation of what you expect the code to do.

Try an approach like this:

Result = cell(1, 3000);  % Maximum size
iR     = 0;
for iA = 1:numel(A)
   C = A(iA).C;
   if isfield(C, 'var_a')
     for iC = 1:numel(C)
        iR = iR + 1;
        Result{iR} = C(iC).var_a;
     end
   end
end
