于是Graphics3D[Arrow[{{0, 0, 0}, {1, 1, 1}}]]可以画出起点在原点的（1,1,1）向量
matlab帮助文件给出的plot::VectorField3d（）命令为什么用不成？因为该函数是不能在matlab运行界面，而只能在 MuPAD界面中运行。 MuPAD 是matlab一个功能比较强大的符号计算辅助程序，其计算功能类似Maple，Mathematica等数学软件。如何使用 MuPAD ，可以先在matlab命令窗口中输入>>mupad，然后在MuPAD界面...
Basic Examples(3) Define and plot a helix: In[1]:= In[2]:= Out[2]= Compute the Darboux vector of the helix and plot its components: In[3]:= Out[3]= In[4]:= Out[4]= Plot the Darboux vector in space: In[5]:= Out[5]= ...
Since previously we probed OV responses using discrete, 3D objects23, we began by asking whether a flat 2D surface would be sufficient to generate vectorial responses. We used the original Duplo tower object (Supplementary Fig.2b) and varied its volume by either gradually embedding it into the ...
