使用交叉熵最小化方法求解矩阵，求哪位lingo高手或matlab高手帮忙

svanscan

各位大神，我想要计算一个16*16的矩阵，本来想用lingo计算，在网上找了一个类似的程序但是运行出来，结过出错，希望给位走过路过的朋友，给予指点，用lingo 或者是matlab都可以，谢谢了，有些急。有关模型描述包括目标函数和约束条件都在附件里面。lingo的运算程序如下：

" H) ]# e5 r" k+ {A/1..16/:ai；
2 `- }% O" |# _B/1..16/:bj;
links(A,B):X,X0;
$ E6 m% {! v  H; Y9 ]5 `!X1=X_*;
endsets

end

lingo运行程序中的约束条件应该为：
!约束条件；
@for(A(i):@sum(B(j):X(i,j))=X(i,i)+ai(i););
@for(B(j):@sum(A(i):X(i,j))=X(j,j)+bj(j););
% U2 g* l9 u9 q! d& c@for(links(i,j):X0(i,j)=@if(i#EQ#j,0,ai(i)*bj(j)));
end
