+## Scatter plot of the columns of one matrix against another.
+##
+## Given the arguments @var{x} and @var{y}, that have a matching number of
+## rows, @code{plotmatrix} plots a set of axes corresponding to
+##
+## @example
+## plot (@var{x}(:, i), @var{y}(:, j))
+## @end example
+##
+## Given a single argument @var{x} this is equivalent to
+##
+## @example
+## plotmatrix (@var{x}, @var{x})
+## @end example
+##
+## @noindent
+## except that the diagonal of the set of axes will be replaced with the
+## histogram @code{hist (@var{x}(:, i))}.
+##
+## The marker to use can be changed with the @var{style} argument, that is a
+## string defining a marker in the same manner as the @code{plot} command.
+##
+## If the first argument @var{hax} is an axes handle, then plot into this axis,
+## rather than the current axes returned by @code{gca}.
+##
+## The optional return value @var{h} provides handles to the individual
+## graphics objects in the scatter plots, whereas @var{ax} returns the
+## handles to the scatter plot axis objects.  @var{bigax} is a hidden
+## axis object that surrounds the other axes, such that the commands
+## @code{xlabel}, @code{title}, etc., will be associated with this hidden
+## axis.  Finally, @var{p} returns the graphics objects associated with
+## the histogram and @var{pax} the corresponding axes objects.
+##

+## @example
+## plotmatrix (randn (100, 3), "g+")
