fmincon 优化出错，请各位哥哥姐姐帮帮忙。

Local minimum possible. Constraints satisfied.

fmincon stopped because the size of the current step is less than the default value of the step size tolerance and constraints are

satisfied to within the default value of the constraint tolerance.

Optimization stopped because the relative changes in all elements of x are less than options.StepTolerance = 1.000000e-10, and the relative maximum constraint violation, 0.000000e+00, is less than options.ConstraintTolerance = 1.000000e-06.

Optimization Metric Options

max(abs(delta_x./x)) = 7.64e-11 StepTolerance = 1e-10 (default)

relative max(constraint violation) = 0.00e+00 ConstraintTolerance = 1e-06 (default)
