自学教程：matlab xlabel位置的设置方式

xlabel(‘time',‘FontSize',12);

xlabel(‘time',‘position',[900,1870],‘FontSize',12);

pos=axis;%取得当前坐标轴的范围，即[xmin xmax ymin ymax]xlabel(‘time',‘FontSize',12, ‘Position',[pos(2) pos(3)])x=0:pi/50:2*pi;y=sin(x);plot(x,y);pos=axis;%取得当前坐标轴的范围，即[xmin xmax ymin ymax]xlabel('x轴','position',[pos(2) 1.15*pos(3)]);%设置x轴标签的文本在图的右下方，1.15这个值根据自己的需要可以调整形成的图
