I tried to evaluate this function but I am getting this error Failure in initial objective function evaluation.

FMINUNC cannot continue.

Please what is the best way to evaluate this function

`f = x(2)^2*x(9)^2 + x(2)^2*x(9) + x(2)^3*x(9) - x(3)*x(5)*x(9)^2 + x(6)*x(8)*x(9)^2 + x(6)*x(8)*x(9)^3 + x(2)*x(6)*x(8)*x(9)^2;`
