Failure in initial nonlinear constraint function evaluation. FMINCON cannot continue.初始非线性约束函数评价失败。

出现这个情况是因为非线性约束函数发生了错误，编译时失败
比如,这里第12行的t(i,j)=t(i,j)/(((co(i)-co(j))^2+(si(i)-si(j))^2);，多了一个‘）’，
Failure in initial nonlinear constraint function evaluation. FMINCON cannot continue.初始非线性约束函数评价失败。改为` t(i,j)=t(i,j)/((co(i)-co(j))^{2+(si(i)-si(j))}2);后即可正常运行
