quiver2.m v1.2 (Nov 2009)

30 Jun 2009 (Updated 12 Nov 2009)

Code covered by the BSD License

Same as QUIVER, QUIVER3 or FEATHER but with colored, normalized, widened and ARROW's!

File Information
Description	This program use QUIVER/QUIVER2 to generate a vector field specialized plot and then customizes the arrows according to its length. Just type >> quiver2(U,V) and that's it. You get - customized arrows - NaNs ignored and - real (U,V) angles with respect to your print/screen. To use only 7 colors use >> quiver2(U,V,'c=',jet(7)) or your own colormap if you have my CMAPPING >> quiver2(U,V,'c=','rygb') To not normalize the length and draw all lines with the same length use: >> quiver2(U,V,'n=',0,'w=',1) To customize the arrows download ARROW by Erik Johnson here at the FileExchange and use: >> quiver2(U,V,'a@','fancy') Of course x,y,z may be used, as well as U,V,W and the S,'filled' normal options of QUIVER, besides of others '=' and '@' options as well. To use it as FEATHER use >> quiver2(U,V,'t=','feather') or >> quiver2(x,[],U,V) Recommended to download also my CMAPPING and TLABEL for better use of this function. Enjoy it! Bugs reports and comments will be very appreciated!
