%  t_ifft_ua: Adjoint of Unbiased Fast Fourier Transform
%  	y=t_ifft_ua(x)
%  Inputs
% 	x	dyadic row vector
%  Outputs
% 	y	dyadic column vector
%  Description
% 	View the entries of x as containing
% 	   x'(-n/2), ... , x'(n/2-1)
%    This routine makes an array y containing
%  the values
% 	   y'(-n/2), ... , y'(n/2-1)
%  where
% 	   y'(k) = n^-1 * Sum( x'(j) exp( 2*pi*i*k*j/n) : -n/2 <= j < n/2)
