用matlab绘制三维向量场，可以使用quiver3函数来完成。如z = y^2 - x^2的三维向量场 x =-3:0.5:3;y =-3:0.5:3;[X,Y] = meshgrid(x, y);Z = Y.^2 - X.^2;[U,V,W] = surfnorm(Z);figure(1)quiver3(Z,U,V,W)view(-35,45)xlabel('x'),ylabel('y'),zlabel('z'...
plot(X,Y) plots vector Y versus vector X. If X or Y is a matrix, then the vector is plotted versus the rows or columns of the matrix, whichever line up. If X is a scalar and Y is a vector, disconnected line objects are created and plotted as discrete points vertically at ...
plotvec(X)only takes a matrixXand plots eachith vector inXwith marker'+'using the indexias the color coordinate. Examples Plot Vectors with Different Colors This example shows how to plot four 2-element vectors. x = [ 0 1 0.5 0.7 ;...-1 2 0.5 0.1]; ...
>> plot(x, y) >> x = 0: pi/20: 2*pi; >> y = cos(x); >> plot(x, y) >> clear x; >> y = cos(0: pi/20: 2*pi) >> plot(y) 同时执行两个画图命令,第二次画图会把第一次画图覆盖掉: >> plot(cos(0: pi/20: 2*pi)); ...
1.quiver函数 一般用于绘制二维矢量场图,函数调用方法如下: 该函数展示了点(x,y)对应的的矢量(u,v)。其中,x的长度要求等于u、v的列数,y的长度要求等于u、v的行数。在绘制图像的过程中,通常用 meshgrid 来生成所需的网格采样点。 下面举几个例子: 例1:一个最简单
Matlab的plot函数非常的强大,进行数据显示的效果非常的好,但是经常使用Opencv的同学如果每次将计算之后的数据导入到Matlab里显示又比较麻烦,因此决定写一类似于plot的C函数,用于在OpenCV中进行数据显示。设计一个Plot类,项目位于github上https:///libing64/CPlot ...
In this chapter, the vector plot (quiver) in MATLAB is presented and described. In this regard, several examples and exercises for each section of the chapter are presented. The exercises that include writing the codes, executing them, and achieving the results need to be done by students to...
