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: ft_preproc_resample.m
    path of file: ./repos/spm12/external/fieldtrip/preproc
    
    the code of the file until where you have to start completion: function [datout, tim, Fnew] = ft_preproc_resample(dat, Fold, Fnew, method)

% FT_PREPROC_RESAMPLE resamples all channels in the data matrix
%
% Use as
%   dat = ft_preproc_resample(dat, Fold, Fnew, method)
% where
%   dat    = matrix with the input data (Nchans X Nsamples)
%   Fold   = scalar, original sampling frequency in Hz
%   Fnew   = scalar, desired sampling frequency in Hz
%   method = string, can be 'resample', 'decimate', 'downsample', 'fft'
%
% The resample method applies an anti-aliasing (lowpass) FIR filter to
% the data during the resampling process, and compensates for the filter's
% delay. For the other two methods you should apply an anti-aliassing
% filter prior to calling this function.
