%                 calculate absolute values of power density (W/m^2)
%
% exdoubleslit....Example using plot_field_slice to illustrate the classic

%                 It also includes use of the calculate patch efficiency function. 
%
% exanim1/2/3.....Examples using plot_wave_anim to make and show movies of wave
%                 propagation. IMPORTANT : These examples are likely to be very
%                 dependent on Matlab version and graphics card. If you have problems
%                 running old versions of Matlab on new machines, try reducing the 
%                 colour range on your display driver e.g. 16bit instead of 32 or 24bit.
