Combining Figures in One Window
The command
subplot
divides the figure window into an array of smaller
figures. The first two arguments give the dimensions of the array of sub-
plots, and the last argument gives the number of the subplot (counting left
to right across the first row, then left to right across the next row, and so on)
in which to put the next figure. The following example, whose output appears
as Figure 5-8, produces a 2
