a=struct('field1',1,'field2',2,'field3',5)
b=struct('field1',3,'field3',4,'field4',6)
f1=fieldnames(a)
f2=fieldnames(b)
f=intersect(f1,f2)
a=rmfield(a,f)
b=rmfield(b,f)

U can use the isequal command to compare between structs.
tf = isequaln(A,B)
And if the result is 1,u can remove those fieldname like for example:
function B = column_removal(A,n)
A = [1 2 3; 4 5 6];
n=2;
A(:,n)=[];
B = A;
end
In this example u will be removing the 2nd coulmn.

Yes, it can, and it will tell you whether the two structures have the exact same field names and field values.
It won't give you the list of fields that have the same name.
Your example of column removal has nothing to do with structures.
Note: I'm not belittling your answer as the OP is obviously happy with it since he accepted it. But if somebody searches the forum for a way to remove matching field names, I'd rather they went to the correct answer to that problem.
