You can't use this kind of comparison on structure arrays.

It sounds like you can use ismember() but you have to make the comparison outside of a structure array.

For example:

A = 1:3;
B = 2;
if any(ismember(A,B))
disp('True');
else
disp('False');
end

I realize you are trying to also capture the similar values, (not the simple thing I have done), but the main problem you are facing is trying to make the comparison directly on structure arrays.

And you meant to type 'eq' (for equals) in your title, not 'eb'
