feather - Plot velocity vectors

GUI Alternatives

Use the Plot Selector to graph selected variables in the Workspace Browser and the Plot Catalog, accessed from the Figure Palette. Directly manipulate graphs in plot edit mode, and modify them using the Property Editor. For details, see Working in Plot Edit Mode, and The Figure Palette in the MATLAB^® Graphics documentation, and also Creating Graphics from the Workspace Browser in the MATLAB Desktop documentation.

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 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);
