+%% @deftypefnx {Function File} {@var{h} =} drawLine (@var{line}, @var{param},@var{value})
+%% Draw the line on the current axis.
+%%
+%%   Draws the line LINE on the current axis, by using current axis to clip
+%%   the line. Extra @var{param},@var{value} pairs are passed to the @code{line} function.
+%%   Returns a handle to the created line object. If clipped line is not
+%%   contained in the axis, the function returns -1.
+%%
+%% Example
+%%
+%% @example
+%%   figure; hold on; axis equal;
+%%   axis([0 100 0 100]);
+%%   drawLine([30 40 10 20]);
+%%   drawLine([30 40 20 -10], 'color', 'm', 'linewidth', 2);
+%% @end example
