** Warning ** 8 variables were initialized close to the internal
               infinity = 1.000000E+10. Were moved to 9.900000E+09.


** Warning **  The variance of the derivatives in the initial
                point is large (= 4.4 ). A better initial
                point, a better scaling, or better bounds on the
                variables will probably help the optimization.


** Infeasible solution. A variable has reached 'Infinity'.
    Largest legal value (Rtmaxv) is 1.00E+10

    The allowable range can be changed with option:

    Rtmaxv=x.xxe+xx


希望懂的大神可以指点一下，这个错误怎么修改。卡在这好久了
