Why am I not getting the expected result?

I have the function listed at the bottom of this post which is supposed to return a matrix that has the same size of a matrix `x` with pixels that had a degree of membership `y`=1 to `1` and the other pixels to `0`.

But, when I ran the function I didn't get the expected results as follows (why is that?):

        >> 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];

    >> pixel_val(x,y)

    ans =

         0     0     0
         0     0     0
         0     0     0
         0     0     0
         0     0     0
         1     1     1
         0     0     0

            function c = pixel_val(x, y)
            [ii,jj]=find(y==1); 
            x(ii,jj)=1; 
            [ii2,jj2] = find (y~=1); 
            x(ii2,jj2)=0;   
            c = x;
            end

Thanks.

You don't need to create a function for this

x=zeros(size(y))
x(y==1)=1

and x is not used in your code

It was explained for you already. Read http://www.mathworks.co.uk/matlabcentral/answers/64472-one-function-returns-the-correct-results-the-opposite-not-why#answer_76075
