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'...
