Check for array equality?

How can I check if indices of three arrays are equal and make those indices all zero if they are equal.

Please provide a short example of your request. E.g., give three arrays and the desired output.

Its not for a specific example, its more like a function where I would have 3 arrays and then would check it. Like [1,2,3;4,5,6] and [1,3,6;6,3,7] and [1,2,5;9,8,7]. But those dimensions and numbers could be anything so the solution would have to work in general.

Not sure what the problem is. Why not just this?

ind = (A==B) && (A == C);
A(ind) = 0;
B(ind) = 0;
C(ind) = 0;

If this is not the answer, then you need to explain yourself FAR more clearly.
