25 ## Scatter plot of the columns of one matrix against another.
26 ##
27 ## Given the arguments @var{x} and @var{y}, that have a matching number of
28 ## rows, @code{plotmatrix} plots a set of axes corresponding to
29 ##
30 ## @example
31 ## plot (@var{x}(:, i), @var{y}(:, j))
32 ## @end example
33 ##
34 ## Given a single argument @var{x} this is equivalent to
35 ##
36 ## @example
37 ## plotmatrix (@var{x}, @var{x})
38 ## @end example
39 ##
40 ## @noindent
41 ## except that the diagonal of the set of axes will be replaced with the
42 ## histogram @code{hist (@var{x}(:, i))}.
43 ##
44 ## The marker to use can be changed with the @var{style} argument, that is a
45 ## string defining a marker in the same manner as the @code{plot} command.
46 ##
47 ## If the first argument @var{hax} is an axes handle, then plot into this axis,
48 ## rather than the current axes returned by @code{gca}.
49 ##
50 ## The optional return value @var{h} provides handles to the individual
51 ## graphics objects in the scatter plots, whereas @var{ax} returns the
52 ## handles to the scatter plot axis objects. @var{bigax} is a hidden
53 ## axis object that surrounds the other axes, such that the commands
54 ## @code{xlabel}, @code{title}, etc., will be associated with this hidden
55 ## axis. Finally, @var{p} returns the graphics objects associated with
56 ## the histogram and @var{pax} the corresponding axes objects.
57 ##
58 ## Example:
59 ##
60 ## @example
61 ## plotmatrix (randn (100, 3), "g+")
