** Feather plot. **

** FEATHER(Z) draws a graph that displays the angle and magnitude **

** of the complex elements of Z as arrows emanating from equally **

** spaced points along a horizontal axis. **

** **

** **

** FEATHER(X,Y) is equivalent to FEATHER(X+i*Y). It displays the **

** feather plot for the angles and magnitudes of the elements of **

** matrices X and Y. **

** **

** **

** FEATHER(Z,'S') and FEATHER(X,Y,'S') use line style 'S' where **

** 'S' is any legal linetype as described under the PLOT command. **
