Remove duplicate sets of coordinates

I have an array of x,y,z coordinates and need to remove any duplicate points. I have tried the unique command but I just remove all duplicate x's or y's or z's, rather than the points where all three are duplicated.

I have tried to give an example of my code below with an 'ideal' output.

x= [1; 2; 2; 4; 4; 4; 1; 1]
y= [0; 0; 0; 3; 3; 3; 0; 0]
z= [5; 1; 1; 1; 3; 3; 1; 5]  
Input= [x; y; z]
Desiredoutput= [...
1 0 5
2 0 1 
4 3 1
4 3 3 
1 0 1]
