MATLAB fsolve求解非线性方程组的问题

function y=myfun(x)
y(1)=x(1)*110^x(2)-x(1)*170^x(2)-3650;
y(2)=x(1)*70^x(2)-x(1)*130^x(2)-9000;
x0=[1 1];
x=fsolve('myfun',x0),optimset('display','iter','MaxFunEvals',1000);
弹出了fsolve stopped because it exceeded the function evaluation limit,

Answer 1

在我的机器上运行，没问题：
Optimizer appears to be converging to a minimum that is not a root:
Sum of squares of the function values is > sqrt(options.TolFun).
Try again with a new starting point.

是不是你的Matlab版本低的原因？我用的是R2008a，Matlab7.6.0
