place array in a matrix

Hello, I have these points:

x1 = (1,0), x2 = (0.5,1), x3 = (0.5,1.5), x4 = (0, -1), x5 = (-1,1), x6 = (0.5, -1)

How do I go about generating a 6 x 6 matrix with entries

x1'x1  x1'x2  x1'x3  x1'x4  x1'x5  x1'x6
x2'x1  x2'x2  x2'x3  x2'x4  x2'x5  x2'x6
x3'x1  x3'x2  x3'x3  x3'x4  x3'x5  x3'x6
x4'x1  x4'x2  x4'x3  x4'x4  x4'x5  x4'x6
x5'x1  x5'x2  x5'x3  x5'x4  x5'x5  x5'x6
x6'x1  x6'x2  x6'x3  x6'x4  x6'x5  x6'x6

Perhaps I'm misunderstanding but if

 x = [1.0000         0
      0.5000    1.0000
      0.5000    1.5000
           0   -1.0000
     -1.0000    1.0000
      0.5000   -1.0000];

which is a 6x2 array, then wouldn't

 x*x'

be the desired 6x6 array?
