%  dct2_iv -- 2-dimensional discrete cosine transform (type IV) -- with a twist
%   Usage
%     c = dct2_iv(x)
%   Inputs
%     x     2-d image (n by n array, n dyadic)
%   Outputs
%     c     2-d cosine transform
% 
%   Description
%     A two-dimensional DCT is computed for the
%     array x. To reconstruct, use the same function:
%           x = dct2_iv_twist(c)
