+## Plots in polar plot defined by a function. The function @var{f} is either
+## a string, inline function or function handle with one arguments defining 
+## the function. By default the plot is over the domain @code{0 < @var{x} < 
+## 2*pi} with 60 points. 
+##
+## If @var{dom} is a two element vector, it represents the minimum and maximum
+## value of both @var{t}. @var{n} is a scalar defining the number of points to 
+## use.
+##
+## The optional return value @var{h} provides a list of handles to the 
+## the parts of the vector field (body, arrow and marker).
