MATLAB: Check for array equality

arrayequalityremove

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

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.

A = [1,2,3
     4,5,6
     7,8,9];
% Add third dimension
A(:,:,2) = A+9; 
% Index
ind = [2,3,2];
ind = num2cell(ind);
A(sub2ind(size(A),ind{:}))
