Hi Ma'mon,

Try the attached code with TOMLAB:

x = tom('x',6,1);

resid = [(x(1)^2)+74.201-(-17.228*x(1))+(x(2)^2)+5.341-(4.622*x(2))+
(x(3)^2)+165.431-(25.724*x(3))-1398.760;
(x(4)^2)+74.201-(-17.228*x(4))+(x(5)^2)+5.341-(4.622*x(5))+
(x(6)^2)+165.431-(25.724*x(6))-750.760;
(x(1)^2)+32.217-(-11.352*x(1))+(x(2)^2)+49.323-(-14.046*x(2))+
(x(3)^2)+341.289-(36.948*x(3))-858.490;
(x(4)^2)+32.217-(-11.352*x(4))+(x(5)^2)+49.323-(-14.046*x(5))+
(x(6)^2)+341.289-(36.948*x(6))-327.610;
(x(1)^2)+13.542-(7.360*x(1))+(x(2)^2)+68.013-(16.494*x(2))+
(x(3)^2)+45.239-(13.452*x(3))-1608.010;
(x(4)^2)+13.542-(7.360*x(4))+(x(5)^2)+68.013-(16.494*x(5))+
(x(6)^2)+45.239-(13.452*x(6))-912.040;
x(1)^2-(2*x(1)*x(4))+x(4)^2+x(2)^2-(2*x(2)*x(5))+x(5)^2+x(3)^2-
(2*x(3)*x(6))+x(6)^2-224.101];

x0 = [1; 1; 1; 1; 1; 1];

options = struct;
options.norm = 'L2';
options.type = 'cls';
Prob = sym2prob(resid,[],{x == x0},options);
Prob.LS.y = zeros(7,1);
Result = tomRun('multiMin', Prob, 1);
