MATLAB: How to write the following matrix

matrixmatrix array

 if true
A = [x(1)^2 x(1)*y(1) y(1)^2 x(1) 1;
     x(2)^2 x(2)*y(2) y(2)^2 x(2) 1;
     x(3)^2 x(3)*y(3) y(3)^2 x(3) 1;
     x(4)^2 x(4)*y(4) y(4)^2 x(4) 1;
     x(5)^2 x(5)*y(5) y(5)^2 x(5) 1;
     x(6)^2 x(6)*y(6) y(6)^2 x(6) 1;
     x(7)^2 x(7)*y(7) y(7)^2 x(7) 1;
     x(8)^2 x(8)*y(8) y(8)^2 x(8) 1;
     x(9)^2 x(9)*y(9) y(9)^2 x(9) 1;
     x(10)^2 x(10)*y(10) y(10)^2 x(10) 1 ]  
end
The integers 1-10 are meant to be subscripts. I've tried using the syms and repmat functions but have not gotten anywhere further.

x = sym('x', [10 1]);
y = sym('y', [10 1]);
 if true
A = [x(1)^2 x(1)*y(1) y(1)^2 x(1) 1;
     x(2)^2 x(2)*y(2) y(2)^2 x(2) 1;
     x(3)^2 x(3)*y(3) y(3)^2 x(3) 1;
     x(4)^2 x(4)*y(4) y(4)^2 x(4) 1;
     x(5)^2 x(5)*y(5) y(5)^2 x(5) 1;
     x(6)^2 x(6)*y(6) y(6)^2 x(6) 1;
     x(7)^2 x(7)*y(7) y(7)^2 x(7) 1;
     x(8)^2 x(8)*y(8) y(8)^2 x(8) 1;
     x(9)^2 x(9)*y(9) y(9)^2 x(9) 1;
     x(10)^2 x(10)*y(10) y(10)^2 x(10) 1 ]  
end
