请问这个求平均值程序为何出错
model:sets:
si/1..5/;
sj/1..3/:mean;
sij(si,sj):plot;
endsets
@for(sj(j):mean=@sum(si(i):plot(i,j))/5);
data:
plot=1 2 3 4 5
6 7 8 9 10
11 12 13 14 15;
enddata目的就是要求出plot每一行的平均值，保存为mean，可是答案却是mean=，不知哪里出错了……
model:
sets:
si/1..3/:MEAN;
sj/1..5/;
sij(si,sj):plot;
endsets
@for(sI(I):mean(I)=@sum(sJ(J):plot(i,j))/5);
data:
plot=1 2 3 4 5
6 7 8 9 10
11 12 13 14 15;
enddata
