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:
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 Online에서 열기 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. x = -4:0.3:4; ...
A quiver plot is a plot of a vector field. It is also called a flow plot. Arrows show the direction of the field, with the lengths of the arrows showing the relative sizes of the field strength. For details on quiver plots, see quiver. ...
have 4 vectors x,z,dx,dz which respectively are coordinate of x,coordinate of z, displacement in x direction ,displacement in z direction. I want to plot a vector field graph for displacement, to see the amount and direction of displacement on each point.size of each vector is (110000,1...
