-## usage: subplot (rows, columns, index)
-##        subplot (rcn)
-##
-## NOTE: this will work only with gnuplot installed with
-##       multiplot patch (or version 3.6 beta)
-##
-## Sets gnuplot in multiplot mode and plots in location
-## given by index (there are columns X rows subwindows)

+## @deftypefn {Function File} {} subplot (@var{rows}, @var{cols}, @var{index})
+## @deftypefnx {Function File} {} subplot (@var{rcn})
+## Sets @code{gnuplot} in multiplot mode and plots in location
+## given by index (there are @var{cols} by @var{rows} subwindows).
+## 
 ## Input:
-##
-##   rows   : number of rows in subplot grid
-##   columns: number of columns in subplot grid
-##   index  : index of subplot where to make the next plot
-##
-## If only one arg, then it (crn) has to be three digit value
-## specifying the location in digit 1 (rows) and 2 (columns) and digit
-## 3 is the plot index
-##
-## The plot index runs row-wise,i.e., first all the columns in a row
-## are filled and then the next row is filled
-##
-## For example, plot with 4 X 2 grid, will have plot indices running as
+## 
+## @table @var
+## @item rows
+## Number of rows in subplot grid.
+## 
+## @item columns
+## Number of columns in subplot grid.
+## 
+## @item index
+## Index of subplot where to make the next plot.
+## @end table
+## 
+## If only one argument is supplied, then it must be a three digit value
+## specifying the location in digits 1 (rows) and 2 (columns) and the plot
+## index in digit 3.
+## 
+## The plot index runs row-wise.  First all the columns in a row are filled
+## and then the next row is filled.
