I am using MATLAB to create a scene generation program to simulate a 
missile flight.  I am having difficulties interpolating colors using 
the patch command.  This is what I currently have

for k=1:length(basex)-1 
        polygon=patch([basex_s(k) basex_s(k+1) tip_s(1)],[basey_s(k) 
basey_s(k+1) tip_s(2)],[basez_s(k) basez_s(k+1) tip_s(3)],[1 0 0]);  
end  

which plots the target as a red cone.  What I would like to do is 
specify a color for each vertex and have Matlab interpolate the colors 
for each face.  Any help would be greatly appreciated.
