You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Adj_USFFT.m
    path of file: ./repos/CS_MoCo_LAB/reconstruction/matlab/CS_LAB_matlab/utils/utils_TRAFO/CurveLab-2.1.3/fdct_usfft_matlab/USFFT
    
    the code of the file until where you have to start completion: function x = Adj_USFFT(n,y,omega,D,L,center)
% USFFT_simple -- 1d adjoint unequispaced Fourier transform
% Usage:
%   x = USFFT(n,y,omega,D,L,center)
% Inputs:
%   n      length of output x
%   y	   vector of length m, 
%   omega  vector of sampled frequencies (length m)
%   center 0 for unbiased FT, 1 otherwise
% Outputs:
%   x      vector of length n
% Description:
%  Evaluates the adjoint of the FT
%   
%  If center = 0, 
%
%  x(t) = sum_{k} exp(i omega_k t) y(k), -n/2 <= t < n/2
%
%  If center = 1, 
%
%  x(t) = sum_{k} exp(i omega_k t) y(k), 0 <= t < n
