: feather (u, v)
: feather (z)
: feather (…, style)
: feather (hax, …)
: h = feather (…)

Plot the (u, v) components of a vector field emanating from equidistant points on the x-axis.

If a single complex argument z is given, then u = real (z) and v = imag (z).

The style to use for the plot can be defined with a line style style of the same format as the plot command.

If the first argument hax is an axes handle, then plot into this axis, rather than the current axes returned by gca.

The optional return value h is a vector of graphics handles to the line objects representing the drawn vectors. 

phi = [0 : 15 : 360] * pi/180;
feather (sin (phi), cos (phi));

See also: plot, quiver, compass.
