Now you can get node characteristics and set new values for certain node properties.
For example, you can change the position of the automobile by using Automobile,
which is the fourth node in the virtual world.

Access the fields of the Automobile node by typing
fields(myworld.Automobile)
or
fields(mynodes(10));
The MATLAB Command Window displays information like the following table.
