"white""w"[1 1 1] To improve performance, the function automatically downsamples the rendered point cloud when you rotate, pan, or zoom in or out by clicking the mouse. Downsampling is not applied for zoom in or out by using the mouse scroll mechanism. When using data tips, the figure...
For example, the first arrow originates from the point X(1) and Y(1), extends horizontally according to U(1), and extends vertically according to V(1). By default, the quiver function scales the arrow lengths so that they do not overlap. example quiver(U,V) plots arrows with ...

This MATLAB function plots the implicit function defined by f(x,y) = 0 over the default interval [-5 5] for x and y.
plot(vector1,vector2)可以用来画两个矢量的二维图,例如 x=1:0.1:2*pi; plot(x,sin(x))可以画正弦函数在0-2pi的上的图像。 plot函数可以接一些参数,来改变所画图像的属性(颜色,图像元素等)。下面是一些属性的说明 b blue(蓝色). point(点)- solid(实线) g green(绿色)o circle(圆圈): dotted(点线...
