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'...
VectorFieldPlot[{fx,fy},{x,xmin,xmax},{y,ymin,ymax}] generates a plot of the vector field given by the vector valued function{fx,fy}as a function ofxandy. VectorFieldPlot[{fx,fy},{x,xmin,xmax,dx},{y,ymin,ymax,dy}]
Vector field plots - Boker, McArdle - 2005 () Citation Context ...posed and the mean slope is taken within each box of the grid for all trajectories crossing that box in the grid. The plot of the dark line segments in figure 26.3 is called an empirical slope field (=-=Boker & Mc...
Hi, I want to make a quiver plot for the velocity vector field u ⃗(x,y,z)=(xy,-x,-2y/z). I wrote the following code: 테마복사 [x, y, z] = meshgrid([-5 : 0.1 : 5]); u = x .* y; v = -x; w = -2 * y ./ ...
VectorFieldPlot A python module for creating SVG images of electric and magnetic field lines for user defined charge and current configurations. This module is an adaptation of the code written by Geek3 to create high quality, physically correct images of electric and magnetic field lines. http:...
StreamPlot[{vx, vy}, {x, xmin, xmax}, {y, ymin, ymax}] generates a stream plot of the vector field {vx, vy} as a function of x and y. StreamPlot[{{vx, vy}, {wx, wy}, ...}, {x, xmin, xmax}, {y, ymin, ymax}] generates plots of several vector fields. Stream

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
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:
I would like to know how it is possibile to plot a 2D contour with a tangential vector field. In detail I have a given velocity profile V (matrix of n-m dimension) as function of X and Y (n-m dimension) and on this plot I want to have the tangential field (streamline) to the ...
