Substituting values in a matrix

Say I have the following two matrices:
>> x = [1 4 3; 6 4 3; 6 9 3; 2 4 3; 5 4 0; 5 3 1; 6 4 7];
>> y = [0 0 1; 1 1 0; 1 1 0; 0 1 1; 0.2 0.8 0.54; 1 1 1; 0 0 0];
Where you can think of `x` as some image, and `y` the *degree of membership* of of each element of `x` to some region of interest.
Say I set those elements in `x` that have degree of membership = 1 to `1` and the other elements to `0` as follows:
x = zeros(size(y));
x(y==1) = 1;
In which case I will have the following output:
0 0 1
1 1 0
1 1 0
0 1 1
0 0 0
1 1 1
0 0 0
Now, for the elements of `0`, how can I substitute their values with the value of `y` in the corresponding location?
Thanks.
