  t=[-pi:pi/30:pi];  确定画图的横坐标区间
  temp=size(X);   得到上面矩阵X的行数和列数；
  
for  i=1:temp(1,1)   这里还可以选择画哪一行的数据
   F=X(i,1);
  for  j=1:3
        F=F+X(i,2*j)*sin(j*t)+X(i,2*j+1)*cos(j*t);
    end
    F=F+X(i,8)*sin(4*t);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    plot(t,F);
    hold on          把所有行的数据都画在一个图上
end
我想在图形上面把每个图形标注一下，以便于区分分类，请问我该怎么修改程序？
