问题描述
我目前正在尝试在MATLAB中绘制一条简单的垂直和水平线.
I am currently trying to plot a simple vertical and horizontal lines in MATLAB.
例如，我想绘制线y = 245.我该怎么办?
For instance, I would like to plot the line y=245. How would I do that?
推荐答案
MATLAB的绘图根据您提供的矢量逐点进行工作.因此，要创建水平线，您需要在保持y不变的同时改变x，对于垂直线则相反:
MATLAB's plotting works on a point-by-point basis from the vectors you give. So to create a horizontal line, you need to varying x while keeping y constant and vice-versa for vertical lines:
xh = [0,10];
yh = [245,245]; % constant
xv = [5,5]; % constant
yv = [0,245*2];
plot(xh,yh,xv,yv);
