求模糊合成算子（·，+）的MATLAB程序，我是要利用这个算子求模糊关系矩

从我的程序里截出来的，有问题再追问吧
switch operator
case 1

for j = 1:num%矩阵 r 的列数
temp(:,j) = min(r(:,j),weight);
end
gar = max(temp);

case 2

for j = 1:num
temp(:,j) =r(:,j).*wei;
end
gar = max(temp)

case 3

for j = 1:num
temp(:,j) = min(r(:,j),wei);
end
gar = sum(temp)

case 4

for j = 1:num
temp(:,j) = r(:,j).*wei;
end
gar = sum(temp)

end
