图像坐标题目添加

figure( 'name', 'write name u wanna be' );

一幅对话框中子图像

subplot( 2, 1, 1 );上面图

subplot( 2, 1, 2 );下面图

subplot(2,2,1) subplot(2,2,2)

subplot(2,2,3) subplot(2,2,4)

-----------我是分界线----------------

每幅图像添加坐标，标题

title（‘name of ur plot ’）

xlabel( 'horizonal position' );

ylabel( 'vertical position' );

zlabel( 'deflectoin' );

legend('deflection and fitting', 'Location', 'NorthEast' ); %右上角添加说明

观察角度改变

view( -41.5, 22 );

-----------------我是分界线-------------------

画完图像，觉得坐标尺度不是自己想要的怎么办

可以用xlim，ylim，zlim修改一下坐标尺度

例如

>> xlim([-0.0015 0.0015]);

同理ylim，zlim
