Question

我要用lingo定义一个0-1矩阵，如何定义？要求每行和每列只有一个1，其余都为0

sets:
e/1..11/;
matrix1/e,e/:a;
endsets

@for(matrix1:@bin(a));
@for(e(i):@sum(e(j):a(i,j))>0);

这是我自己定义的一个 但是总是报错，LINGO’s predefined functions generally expect a specific number of arguments. You’ll get this message if you are passing an incorrect number of arguments. Check the syntax of the function in question.

Answer 1

sets:
e/1..11/;
matrix1(e,e):a;
endsets

@for(matrix1:@bin(a));
@for(e(i):@sum(e(j):a(i,j))>0);

自己看好派生集怎么定义的

Answer 2

@for(e(i):@sum(e(j):a(i,j))>0);
改成
@for(e(i):@sum(matrix1(i,j):a(i,j))>0);
