How can i solve non-linear equation?

Well, i tried to solve this equation but i got few errors.

My equation is this :

%MAPPING x(1)=x x(2)=y x(3)=z

f= @(x) [3*x(1)*x(2) + x(2) - x(3) - 12 ; x(1) + x(2)*x(1)^2 + x(3) -12 ; x(1) -x(2) -x(3) +2 ];

x1 = [1;1;1];

fsolve(f,x1)

But i got these errors :

Error using vertcat Dimensions of matrices being concatenated are not consistent.

Error in odev22>@(x)[3*x(1)*x(2)+x(2)-x(3)-12;x(1)+x(2)*x(1).^2+x(3),-12;x(1),-x(2),-x(3),+2]

Error in fsolve (line 230) fuser = feval(funfcn{3},x,varargin{:});

Error in odev22 (line 5) fsolve(f,x1)

Caused by: Failure in initial objective function evaluation. FSOLVE cannot continue.

    % code-No Error
f=@(x) [3*x(1)*x(2)+x(2)-x(3)-12; x(1)+x(2)*x(1)^2+x(3)-12; x(1)-x(2)-x(3)+2];
x1=[1;1;1];
fsolve(f,x1)

i can't believe the problem was "spaces" between values at equation. Anyway thank you much
