Simple 3D vector plotting

I need to make a 3D drawing.

3D drawing consists of:

1 vectors,

2 lines,

3 arcs for angle between two vectors or lines vector,

4 vector, line, arc labels.

Label requirements:

1 Greek symbols (phi, alpha, theta, ...)

2 showing a fraction ability (phi/2)

3 font style such as italic, bold, ...

Can somebody write a snippet of code for me, because I am newbie at matlab, it will be very helpful? Can you please write a code which display two 3D vectors with labels (letter and low index) and angle between them (arc with label "phi/2"). Thanks in advance.

You're asking quite a lot there. Here are a few functions that will get you going in the right direction:

• For drawing vectors in 3D, you'll probably want to use quiver3. The x, y, and z inputs represent where you want the base of the vector to be drawn and the u, v, and w inputs represent the three components of the vector.
• For drawing straight lines and arcs use line. See the documentation for examples of how to use it.
• For adding labels use text. Again, the documentation has useful examples.

How can I draw a single 3d vector. Cause quiver 3 gives multiple vectors in the 3d plane
