[交流] fmincon 函数使用bug

函数运行出现下面的提示：
fmincon stopped because the size of the current search direction is less than
twice the default value of the step size tolerance but constraints were not
satisfied to within the default value of the constraint tolerance.
关于函数优化停止的进一步提示：
Optimization stopped because the norm of the current search direction , 2.244999e-014, is less
than twice the default value of options.TolX = 1.000000e-006, but the maximum constraint
violation, 4.640455e-006, exceeds the default value of options.TolCon = 1.000000e-006.

Optimization Metric                                        User Options
norm(search direction) =  2.24e-014                      TolX =  1e-006 (default)
max(constraint violation)  =  4.64e-006                TolCon =  1e-006 (default)

遇上这类问题表示什么，然后如果想改的话该怎么修改呢
