3D Plot -
Computer graphics are better for
understanding many types of data
|In these sections you can find many
step-by-step commented guides to
easily develop 3D plots. If you are not familiar with tridimensional
graphics in Matlab, I recommend you start from Part 1;
otherwise, go to the link of your interest.

Matlab provides many powerful instructions for the visualization of 3D
The instructions provided include tools to graph wire-frame
objects, 3D curves,
plot3, meshc, surfc)
The 3D graph functions intended for plotting meshes and surfaces 'mesh'
and their several variants 'meshc',
'meshz', 'surfc', and
take multiple optional input arguments...
In this part, we demonstrate the use of the function 'sphere'. We are
going to draw a unit sphere centered at the origin and generated by
matrices x, y and z, of size 31 x 31 each...

In this example we make a summarization

We’re going to experiment with simple

Summary of 3D Graphics
There are many facilities for
of 3D information or data (x, y, z).
facilities include built-in functions for plotting wire-frame objects,
