Usage
This function divides the current figure into a 2-
dimensional grid, each of which can contain a plot of some
kind. The function has a number of syntaxes. The first
version
subplot(row,col,num)
which either activates subplot number num, or sets up a
subplot grid of size row x col, and then activates num. You
can also set up subplots that cover multiple grid elements
subplot(row,col,[vec])
where vec is a set of indexes covered by the new subplot.
Finally, as a shortcut, you can specify a string with three
components
subplot('mnp')
or using the alternate notation
subplot mnp
where m is the number of rows, n is the number of columns
and p is the index. You can also specify the location of the
subplot explicitly using the syntax
subplot('position',[left bottom width height])
Example
Here is the use of subplot to set up a 2 x 2 grid of plots
--> t = linspace(-pi,pi);
--> subplot(2,2,1)
--> plot(t,cos(t).*exp(-2*t));
--> subplot(2,2,2);
--> plot(t,cos(t*2).*exp(-2*t));
--> subplot(2,2,3);
--> plot(t,cos(t*3).*exp(-2*t));
--> subplot(2,2,4);
--> plot(t,cos(t*4).*exp(-2*t));

Here we use the second form of subplot to generate one
subplot that is twice as large.
--> t = linspace(-pi,pi);
--> subplot(2,2,[1,2])
--> plot(t,cos(t).*exp(-2*t));
--> subplot(2,2,3);
--> plot(t,cos(t*3).*exp(-2*t));
--> subplot(2,2,4);
--> plot(t,cos(t*4).*exp(-2*t));

Note that the subplots can contain any handle graphics
objects, not only simple plots.
--> t=0:(2*pi/100):(2*pi);
--> x=cos(t*2).*(2+sin(t*3)*.3);
--> y=sin(t*2).*(2+sin(t*3)*.3);
--> z=cos(t*3)*.3;
--> subplot(2,2,1)
--> plot(t,x);
--> subplot(2,2,2);
--> plot(t,y);
--> subplot(2,2,3);
--> plot(t,z);
--> subplot(2,2,4);
--> tubeplot(x,y,z,0.14*sin(t*5)+.29,t,10)
--> axis equal
--> view(3)
