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'...
(xn, yn, zn), where each set of vectors represents the X, Y, and Z coordinates of a set of data points in three-dimensional space. Using these coordinates, plot3 can draw multiple independent curves, each of which is drawn according to its corresponding (x, y, z) vector set, ...
在Matlab中,可以使用plot3函数来显示三维数据。plot3函数可以绘制三维曲线、曲面和散点图等。 plot3函数的语法如下: plot3(X, Y, Z) 其中,X、Y和Z分别是三维数据的x、y和z坐标。这些坐标可以是向量、矩阵或网格数据。 下面是plot3函数的一些常见用法和参数说明: ...
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,通常用 meshgrid 来生成所需的网格采样点。 下面举几个例子: 例1:一个最简单的例子,该二维矢量场图中的矢量皆从(0,0)出发,分别指向(1,0) 、(-1,0) 、(0,1) 、(0,...
