Referencing specific dimensions of an array

Hello,
I have a rectangular matrix and I am trying to determine if values in each row are equal. I built a function that will check an array to see if all numbers are equal. I want to avoid using a for loop.
I tried to add a fourth column to an existing matrix with the result of the function.
I tried;
x(:,4)=three(x(:,:))
as well as several other variations. how can I imply to evaluate only each row?

x(:,4) = all(bsxfun(@eq,x(:,1),x(:,2:3)),2)
The fourth column will not be true where the first three columns are equal.
I believe this is what you want. If it's not, exactly what do you want? A small example with inputs->operation->expected output would be ideal
