Purpose 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.
2-742
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 handle axes_handle
instead of the current axes (gca).
h = feather(...) returns the handles to line objects in h.
Examples Create a feather plot showing the direction of theta.
theta = ( 90:10:90)*pi/180;
r = 2*ones(size(theta));
[u,v] = pol2cart(theta,r);
feather(u,v);
