MATLAB: How many times each element of an array have the 1 value after n times assigned different logical values

counting_1valuesMATLAB

I have n same size matrices containing different logical values such as A1, A2, A3 matrices. It also can be considered that a matrix_A was assigned n times with different logical values 1 and 0. Please help to point out how to count the number of times each elements of this A matrix having 1 value. Any suggestion would be much appreciated!
A1 = 1 0 0 1 0 1 0
     0 1 0 1 0 0 0
     0 1 1 0 0 1 0
     0 1 1 0 1 0 1
A2 = 1 0 0 0 0 1 0
     0 1 0 0 0 0 0
     0 1 1 1 0 1 0
     0 1 1 1 1 0 1
A3 = 0 0 0 0 0 1 1
     0 1 1 1 1 0 0
     0 0 0 0 0 0 0
     0 0 0 0 0 0 1

Simple: use one 3D array:
A = cat(3,...
    [1 0 0 1 0 1 0
     0 1 0 1 0 0 0
     0 1 1 0 0 1 0
     0 1 1 0 1 0 1],...
    [1 0 0 0 0 1 0
     0 1 0 0 0 0 0
     0 1 1 1 0 1 0
     0 1 1 1 1 0 1],...
    [0 0 0 0 0 1 1
     0 1 1 1 1 0 0
     0 0 0 0 0 0 0
     0 0 0 0 0 0 1]);
And then:
>> sum(A,3)
ans =
   2   0   0   1   0   3   1
   0   3   1   2   1   0   0
   0   2   2   1   0   2   0
   0   2   2   1   2   0   3
Note: if your arrays are in one cell array C then you can easily conver this into a 3D array:
A = cat(3,C{:});
If you have lots of separate variables, then you need to fix your code design.
