function draxis(translation)
% The function:
% 
%       draxis(translation)
% 
% draws Cartesian axis with 2 arrows 
% in the current 2-dimensional axis. 
% Optional arg <translation> allows 
% to translate the axis; default is [0,0]. 

if nargin<1, translation = [0,0]; end;

hold on;
arrow([translation(1),translation(2)],[translation(1)+1,translation(2)  ]);
arrow([translation(1),translation(2)],[translation(1)  ,translation(2)+1]);
