matlab帮助文件给出的plot::VectorField3d（）命令为什么用不成？因为该函数是不能在matlab运行界面，而只能在 MuPAD界面中运行。 MuPAD 是matlab一个功能比较强大的符号计算辅助程序，其计算功能类似Maple，Mathematica等数学软件。如何使用 MuPAD ，可以先在matlab命令窗口中输入>>mupad，然后在MuPAD界面...
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'...
In addition, the isosurface function can also accept other parameters, such as: isosurface(V,isovalue), where V is a three-dimensional array representing the value of a scalar field. At this point, the isosurface function automatically creates a grid and uses the default coordinate vector.5. fp...
how to plot a gradient vector which is function of x, y, z, i.e. grad(f(x,y,z)). i need three dimensional plot of this function, where x,y,z are variables. still i unable to plot this function. my function is given by x-component=x.y y-component=x.^2+y.^2 z-component...
the number of columns in the matrix directly determines the number of curves drawn, and each column corresponds to an independent curve. For the case where the X, Y, and Z parameters contain both vectors and matrices, the plot3 function requires that the length of the vector must strictly ...

2. SCATTER3 (3D scatter Plot) scatter3(X,Y,Z):This function will create circles at the vector locations of x, y, and z. Example: X, y, z are vector spheres. Code: [X,Y,Z] = SPHERE(10) x = [0.5*X(:); 0.25*X(:); X(:)]; ...
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1:一个最简单的例子,该二维矢量场图中的矢量皆从(0,0)出发,分别指向(1,0) 、(-1,0) 、(0,1) 、(0,...

To plot a vector the plot function is used. Syntax for plotting vector using plot() is: plot(x,y) Here both x and y represent two vectors of equal length. The plot function will create a two-dimensional line plot of the data in y versus the data in x. ...
