MATLAB: Structs in struct, howto access

accessstructvariable

Hello,

I like to access a struct variable. A small example of the variable:

a(1).b.f1 = 11;
a(1).b.f2 = 12;
a(2).b.f1 = 21;
a(2).b.f2 = 22;

Now I like to access field f1 like:

a.b.f1

Matlab returns: Expected one output from a curly brace or dot indexing expression, but there were 2 results.

I expacted an output like

ans =
    11
    21

Is there a work around?

Thank you

arrayfun(@(S) S.b.f1, a(:) )

Iterate over the fieldnames of B to copy them using dynamic field names:

A = struct('f1', 1, 'f2', 2, 'f3', 3);
B = struct('f1', 4, 'f2', 5);
for fn = fieldnames(B)'
   A.(fn{1}) = B.(fn{1});
end

Francesco, loop through the eight cells and use isequal to compare the matrices.
