  在轴箭头绘制坐标空间是很困难的，因为Matlab的内置函数图工程箭头坐标空间。这个函数的轴到图坐标计算及放置在正确的位置注释箭头。它还提供了一个按钮式功能重新同步线和箭头如果调整轴或人物，或变更线的属性。(Plotting an arrow in axis coordinate space can be difficult, since Matlab s built-in arrow function works in figure coordinate space. This function does the axis-to-figure coordinate calculation and places an annotation arrow in the correct location. It also provides a button-down function to re-sync the line and arrow if you resize the axis or figure, or change the line properties.)
