4.4 Clearing the Figure Window
You can clear the plot window by typing clf, which stands for ‘clear
figure’. To get rid of a figure window entirely, type close. To get rid
of all the figure windows, type close all. New figure windows can be
created by typing figure.

4.5 Subplots

To plot more than one set of axes in the same window, use the subplot
command. You can type

subplot(m,n,p)
to break up the plotting window into m plots in the vertical direction
and n plots in the horizontal direction, choosing the pth plot for drawing
into. The subplots are counted as you read text: left to right along the
top row, then left to right along the second row, and so on. Here is an
example (do not forget to use the ↑ key to save typing):
t = 0:.1:2*pi;
subplot(2,2,1)
plot(cos(t),sin(t))
subplot(2,2,2)
plot(cos(t),sin(2*t))
subplot(2,2,3)
plot(cos(t),sin(3*t))
subplot(2,2,4)
plot(cos(t),sin(4*t))
If you want to clear one of the plots in a subplot without affecting
the others you can use the cla (clear axes) command. Continuing the
previous example:
