画出下图: 3.dfield与pplane(多应用于常微分方程) dfield与pplane的原作者是Rice University的John C. Polking,用于解决涉及常微分方程的问题,比较方便,这里可以下载dfield与pplane的.m文件 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...
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'...

I want to plot a velocity field defined in polar coodinates as Vr = -10/r and Vt=10/r (radial and tangent coordinates, respectively), but im having some troubles, below the code that i made. 테마복사 x = -4:0.3:4; y = x; [X, Y] = meshgrid(x,y); Vr = -10./...
div = divergence(X,Y,Z,Fx,Fy,Fz) computes the numerical divergence of a 3-D vector field with vector components Fx, Fy, and Fz. The arrays X, Y, and Z, which define the coordinates for the vector components Fx, Fy, and Fz, must be monotonic, but do not need to be uniformly ...
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 ...

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...
rho = subs(rho,ep0,1); v = -2:0.1:2; [xPlot,yPlot] = meshgrid(v); Ex = subs(E(1),x,xPlot); Ey = subs(E(2),y,yPlot); rhoPlot = double(subs(rho,{x,y},{xPlot,yPlot})); Plot the electric field usingquiver. Overlay the charge density usingcontour. The contour lines...
