Matlab:绘制具有hold on和hold off的子图，在循环中不调用xlabel、ylabel、xlim等

Matlab question: this might be really simple but I can't figure it out...I'm pretty new. I have a plot window, broken up into two subplots, lets call them A and B, which have different labels and limits. I (hold on), make several plots to B, then I (hold off), then start iterating. In the loop, I want to update both A and B with NEW plots, but I want the axis labels, and xlim and ylim to stay the same, WITHOUT having to call xlabel, xlim, etc every iteration.Matlab question: this might be really simple bu
