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.
