%
% FEXGUI        - call of graphical user interface
%
% -----------------------------------------------------------------------------
%
% Main routines 
%

%
% auxiliary functions
%
% MyFunction    - example of matlab routine (singular inner function) 
%
% colscheme     - algorithms for converting complex numbers to colors 
% fldrect       - discrete field of complex numbers, domain of function 
% unitcirc      - vector with discrete points on complex unit circle
% zdomain       - the same as fldrect (former version)
% zplane        - discrete field of points in the entire complex plane
% zplanePP      - the same as zplane (to avoid confusion with existing m-file)
