plsvect - Set arrow style for vector plots

arrowx,arrowy (PLFLT_VECTOR(3plplot), input)
              A  pair  of vectors containing the x and y points which make up the arrow. The arrow is plotted by
              joining these points to form a polygon. The scaling assumes that the x and y points in  the  arrow
              lie  in the range -0.5 <= x,y <= 0.5. If both arrowx and arrowy are NULL then the arrow style will
              be reset to its default.

       npts (PLINT(3plplot), input)
              Number of points in the vectors arrowx and arrowy.

       fill (PLBOOL(3plplot), input)
              If fill is true then the arrow is closed, if fill is false then the arrow is open.

       Many developers (who are credited at http://plplot.org/credits.php) have contributed to PLplot  over  its
       long history.

       Set the style for the arrow used by plvect(3plplot) to plot vectors.

       Redacted form: plsvect(arrowx,arrowy,fill)

       This function is used in example 22.
