( | arrowx , |

Set the style for the arrow used by plvect to plot vectors.
arrowx, arrowy
(PLFLT_VECTOR, 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
and
arrowx are NULL then
the arrow style will be reset to its default.
arrowy
npts
(PLINT, input)
Number of points in the vectors
and
arrowx
.
arrowy
fill
(PLBOOL, input)
If
is true then the
arrow is closed, if fill
is false then the arrow is open.
fill
Redacted form: plsvect(arrowx, arrowy, fill)
This function is used in example 22.
