matlab 提示Error using vertcat CAT arguments dimensions are not consistent.
for i=1965:1:1970 for j=1:12 a=find(a1(:,2)==i&a1(:,3)==j); b=a1(a,:); c=mean(b(:,5)); d=[d;i,j,c]; end end提示矩阵维度出错,可是维度应该并没有出错啊,我记得原来运行这个程序的时候也没提示这个错误.

你把的初始化一下.例如这样修改：
d=[];
for i=1965:1:1970
for j=1:12
a=find(a1(:,2)==i&a1(:,3)==j);
b=a1(a,:);
c=1;%mean(b(:,5));
d=[d;i,j,c];
end
end
由于你没有给出a1矩阵式什么,没法具体给你调试,问题就是d这里.或者是你的d初始化的不是三列
