% ShowVec(vecs,[nRowPixels,nColPixels])
% 
% OBSOLETE. Use Screen 'PutImage' instead. See GratingDemo.
% 
% MEX file to show column vectors as images.  Image values should be
% in range [0,1].
% 
% Each column of vecs is assumed to represent an image stacked into a
% vector.  This is a convenient format for some image processing
% techniques.
% 
% If nRowPixels and nColPixels are omitted, the image is assumed to
% be square.
% 
% Control returns to Matlab when all of the windows have been closed.
% You cannot leave an image up and continue on in the Matlab command
% window.

% 8/19/94		dhb		Replace M-file version with MEX-file.
%						dhb		Change of interface.
%						dhb		Link in new version of pixel handling code.
% 7/11/00		dgp		Note obsolescence.
