function a = alim(arg1, arg2)
%ALIM Alpha limits.
%   AL = ALIM             gets the alpha limits of the current axes.
%   ALIM([AMIN AMAX])     sets the alpha limits.
%   ALMODE = ALIM('mode') gets the alpha limits mode.
%   ALIM(mode)            sets the alpha limits mode.
%                            (mode can be 'auto' or 'manual')
%   ALIM(AX,...)          uses axes AX instead of current axes.
%
%   ALIM sets or gets the Alim or AlimMode property of an axes.
