function a = daspect(arg1, arg2)
%DASPECT Data aspect ratio.
%   DAR = DASPECT             gets the data aspect ratio of the
%                                current axes. 
%   DASPECT([X Y Z])          sets the data aspect ratio.
%   DARMODE = DASPECT('mode') gets the data aspect ratio mode.
%   DASPECT(mode)             sets the data aspect ratio mode.
%                                (mode can be 'auto' or 'manual')
%   DASPECT(AX,...)           uses axes AX instead of current axes.
%
%   DASPECT sets or gets the DataAspectRatio or DataAspectRatioMode 
%   property of an axes.
