function a = zlim(arg1, arg2)
%ZLIM Z limits.
%   ZL = ZLIM             gets the z limits of the current axes.
%   ZLIM([ZMIN ZMAX])     sets the z limits.
%   ZLMODE = ZLIM('mode') gets the z limits mode.
%   ZLIM(mode)            sets the z limits mode.
%                            (mode can be 'auto' or 'manual')
%   ZLIM(AX,...)          uses axes AX instead of current axes.
%
%   ZLIM sets or gets the ZLim or ZLimMode property of an axes.
