feather
Plot velocity vectors
Syntax
feather(U,V)
feather(Z)
feather(...,LineSpec)
feather(axes_handle,...)
h = feather(...)
Description
A feather plot displays vectors emanating from equally spaced points along a horizontal axis. You express the vector components relative to the origin of the respective vector.
feather(U,V) displays the
vectors specified by U and V,
where U contains the x components
as relative coordinates, and V contains the y components
as relative coordinates.
feather(Z) displays the
vectors specified by the complex numbers in Z.
This is equivalent to feather(real(Z),imag(Z)).
feather(...,LineSpec) draws
a feather plot using the line type, marker symbol, and color specified
by LineSpec.
feather(axes_handle,...) plots
into the axes with the handle axes_handle instead
of into the current axes (gca).
h = feather(...) returns
the handles to line objects in h.
Examples
Create Feather Plot
Define theta as values between
and
. Define r as a vector the same size as theta.
theta = -pi/2:pi/16:pi/2; r = 2*ones(size(theta));
Create a feather plot showing the direction of theta. Since feather uses Cartesian coordinates, convert theta and r to Cartesian coordinates using pol2cart.
[u,v] = pol2cart(theta,r); feather(u,v)
