如果真的沒辦法的話，我想請教該如何畫出斜格線

Hello Jesse,

I understand that you are trying to visualise the result of addition of 2 vectors in 3-dimensional space.

You can do so by using “plot3” function of MATLAB. It can be achieved by using the following code:

i=[1;0;0];
j=[1;2;0];
A=i+j;
plot3([0,A(1)],[0,A(2)],[0,A(3)]);
grid on
axis 'auto xy'

Since a vector can start and end at any point, I have plotted it from the origin.

You can refer to the following MATLAB documentation to learn more about “plot3” function:

3-D point or line plot - MATLAB plot3 - MathWorks India

Thanks,

Charan.
