Trying to predict equality between cell arrays

I have two cell arrays A and B

A 400 x 1 cell

{1 x 5 categorical

1 x 5 categorical

1 x 5 categorical

.......}

B 400 x 1 cell

{1 x 5 categorical

1 x 5 categorical

1 x 5 categorical

.......}

I tried to do

C = sum(B == A)./numel(A)

And I am getting the following error

Undefined operator '==' for input arguments of type 'cell'.

Then I tried the following

C = sum(B{:} == A{:})./numel(A{:})

And I am getting the folowing error

Error using ==

Too many input arguments.

If you are just testing equality between the whole cells use:

isequal(A,B);

I am not after isequal !

Anyway I got it to work by using a simple for loop.
