% AutoImage -- Image display of object assuming arbitrary values
%  Usage
%    AutoImage(img [,x,y])
%  Inputs
%    img     2-d image
%    x,y     where x and y are vectors, specifies the labeling of
%   	     X- and Y-axes, but produces the same image as AutoImage(img).
%
%  Side Effects
%    The object img, assuming arbitrary values, is scaled to the 
%    range (0,255) and displayed as an image with 256 shades of gray.

%    use GrayImage.
