% PLOTVERT
% Usage: PLOTVERT(tri,col1,col2,col3)
% Inputs:  tri - a vector who components are the vertices of the 
%          triangle to be plotted
%          col1,col2,col3 - colours (in order) for plotting the vertices 

function dum = plotvert(tri,col1,col2,col3)             
    
   P = tri(1);
   Q = tri(2);
   R = tri(3);

   plot(real(P),imag(P),[col1 'o']);     
   plot(real(Q),imag(Q),[col2 'o']);     
   plot(real(R),imag(R),[col3 'o']);     
   dum =[];
