代码：

clear
M = 600;N = 420;p=200;q=2282;
eq = @(x) x^M-(1+q/p)*x^(M-N)+q/p;
options = optimset(‘MaxFunEvals‘,10000,‘MaxIter‘,1000);
x=fsolve(eq,1.2345,options);
r=1-x

问题描述：

No solution found.

fsolve stopped because the relative size of the current step is less than the
default value of the step size tolerance squared, but the vector of function values
is not near zero as measured by the default value of the function tolerance.

<stopping criteria details>

问题解决：

在命令行窗口键入x

得到 x 1.2114

修改原代码x初值为1.2114

运行，就Equation solved.

这个问题应该是迭代的原因，即越来越靠近正确答案。
