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'...
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...
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...
Vector and Matrix Data plot3(X,Y,Z) plots coordinates in 3-D space. To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z ...
Open in MATLAB Online Download plotvec plots all vectors given in a matrix with a vector in each row. Possible are 2D or 3D vectors. Optional a name of the vector can be given in an addional matrix. Than the name and the coordinates of each vector are displayed. ...
MATLAB中矢量场图的绘制 (quiver/quiver3/dfield/pplane) Plot the vector field with MATLAB 2016-09-01 18:20 −1.quiver函数 一般用于绘制二维矢量场图,函数调用方法如下: quiver(x,y,u,v) 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MATLAB中调用dfield,呈现 : 如果我们要绘制常微分方程x′=x2−tx′=x2−t对应的矢量场图,我们可以输入对应的公式与参数值。在这里,上图中默认的常微分方程对应矢量场图: 在MATLAB中调用pplane,呈现 以默认的微分方程为例,可以绘制矢量场图:
MATLAB Online에서 열기 You can calculate the bin averages pretty quickly using discretize and accumarray: Some sample data: 테마복사 npt = 10000; A = [rand(npt,1)*180-90 rand(npt,1)*360-180 rand(npt,1)]; 5-degree bins: 테마복사 latbin = -90:5:90; lonbin...

By default, MATLAB graphics display the divergence of the vector field by the width of the tube. You can also define widths for each tube vertex and thereby map other data to width. This example uses the following techniques: Stream tubes to indicate flow direction and divergence of the vecto...
