calculate equality between adjacent elements in matrix

Hello I have matrix A like that:

    A=[7 7 3 5 6;
       1 1 7 5 6;
       6 6 5 5 5;
       1 1 3 3 3;
       1 1 7 7 7]

I want to move from this matrix 2 times. first from left to right and second from up to bottom. then on the basis of these movements and equality between adjacent elements, matrix B1 and B2 are composed respectively. it means if from left to right movement adjacent elements are equal, the value of corresponding element in matrix B1 is 1. for example in this sample data B1 is like that:

    B1=[1 0 0 0;
        1 0 0 0;
        1 0 1 1;
        1 0 1 1;
        1 0 1 1]

Also matrix B2 is composed on the basis of up to bottom movement like that:

    B2=[0 0 0 1 1;
        0 0 0 1 0;
        0 0 0 0 0;
        1 1 0 0 0]

I hope this is clear. Thank you
