adds a grid to the current plot,
whereas the functions

These are a few examples how MATLAB functions can be used at in the
Command Window to edit the plot. However, the software also supports
various ways to edit all objects in a graph interactively using a computer
mouse. First, the
Edit Mode
of the Figure Window has to be activated by
clicking on the arrow icon. The Figure Window also contains a number of
other options, such as
Rotate 3D
