3.2 Creating 3D Graphs

Matlab offers fancy 3-dimensional line plots and surface graphs.

3.2.1 Creation of 3D Line Plots

There is the function:

3 which its use is similar as with the function:

with the difference that an additional input argument corresponding to the

additional dimension is required (the additional dimension is symbolized as

“z”).

3 is used to plot lines or point coordinates in the 3D space. Let use

the

3 to create a 3D helix:

Matlab’s command:

>> clear; g=linspace(-5*pi,5*pi,200); plot3(sin(g),cos(g),g,'r*-');

>> xlabel('x'); ylabel('y'); zlabel('z'); title('A helix');

3.2.2 Creation of 3D Mesh and Surface Graphs

There are also many commands that lead to the creation of 3D surfaces.

Recall that to create a surface of two variables, at each pair of (x,y) a
