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：
. c2 N4 f( X& x; d+ pmodel:!16家银行；sets：
A/1..16/:ai；
4 n# t1 j' p/ [4 r' H% S& bB/1..16/:bj;
links(A,B):X,X0;
!X1=X_*;
endsets

lingo运行程序中的约束条件应该为：
# [- ~2 O( j7 Z- ?!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););
