subplot(2,2,2)

cla

As long as your subplots are based on an array of 9

9 little plots or

less, you can use a simplified syntax. For example,
subplot(221)
or

subplot 221
are equivalent to
subplot(2,2,1)
. You can mix different

subplot arrays on the same figure, as long as the plots do not overlap:

×

subplot 221

plot(1:10)

subplot 222

plot(0,'*')

subplot 212

plot([1010])

4.6 Three-Dimensional Plots

The
plot3
command is the 3-d equivalent of
plot
:

t = 0:.1:2*pi;

plot3(cos(3*t),sin(3*t),t)

The three dimensional spiral can be better visualised by changing the

orientation of the axes. You can invoke a mouse-based 3-d axis mover

by typing:

rotate3d

If you click the mouse button down on the plot and drag, you can move

the axes and view the plot from any angle. Release the mouse button to

redraw the data. Type
rotate3d
again to turn off this behaviour.
