% @deftypefn {Function File} {} ezplot (@var{f})
% @deftypefnx {Function File} {} ezplot (@var{fx}, @var{fy})
% @deftypefnx {Function File} {} ezplot (@dots{}, @var{dom})
% @deftypefnx {Function File} {} ezplot (@dots{}, @var{n})

% @deftypefnx {Function File} {@var{h} =} ezplot (@dots{})
%
% Plots in two-dimensions the curve defined by @var{f}.  The function
% @var{f} may be a string, inline function or function handle and can
% have either one or two variables.  If @var{f} has one variable, then 
% the function is plotted over the domain @code{-2*pi < @var{x} < 2*pi}  
% with 500 points. 
%
% If @var{f} has two variables then @code{@var{f}(@var{x},@var{y}) = 0}
% is calculated over the meshed domain @code{-2*pi < @var{x} | @var{y}
% < 2*pi} with 60 by 60 in the mesh.  For example
%
% @example
% ezplot (@@(@var{x}, @var{y}) @var{x} .^ 2 - @var{y} .^ 2 - 1)
% @end example
%
% If two functions are passed as strings, inline functions or function
% handles, then the parametric function
%
% @example
% @group
% @var{x} = @var{fx} (@var{t})
% @var{y} = @var{fy} (@var{t})
% @end group
% @end example
%
% is plotted over the domain @code{-2*pi < @var{t} < 2*pi} with 500
% points. 
%
% If @var{dom} is a two element vector, it represents the minimum and maximum
% value of @var{x}, @var{y} and @var{t}.  If it is a four element
% vector, then the minimum and maximum values of @var{x} and @var{t}
% are determined by the first two elements and the minimum and maximum
% of @var{y} by the second pair of elements.
%
% @var{n} is a scalar defining the number of points to use in plotting
% the function.
%
% The optional return value @var{h} provides a list of handles to the 
% the line objects plotted.
