f1=@(x)[x(1)-0.6*sin(x(1))-0.3*cos(x(2)),x(2)-0.6*cos(x(1))-0.3*sin(x(2))];
f2=@(x)[x(1)^2-x(2)^2+x(3)-9,3*x(1)+5*x(2)+6*x(3),x(1)-3*x(2)-6*x(3)-1];
x=fsolve(f1,[0,0])
x2=fsolve(f2,[-1,1,-1])
结果：
Equation solved.
fsolve completed because the vector of function values is near zero
as measured by the default value of the function tolerance, and
the problem appears regular as measured by the gradient.

x =
0.530020372384399 0.714176726861242
No solution found.
fsolve stopped because the last step was ineffective. However, the vector of function
values is not near zero, as measured by the default value of the function tolerance.
