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: spm_eeg_interpolate_artefact.m
    path of file: ./repos/spm/toolbox/MEEGtools
    
    the code of the file until where you have to start completion: function D = spm_eeg_interpolate_artefact(S)
% 'Baseline Correction' for M/EEG data
% FORMAT D = spm_eeg_interpolate_artefact(S)
%

    
function D = spm_eeg_interpolate_artefact(S)
% 'Baseline Correction' for M/EEG data
% FORMAT D = spm_eeg_interpolate_artefact(S)
%
% S        - optional input struct
% (optional) fields of S:
%   S.D    - MEEG object or filename of M/EEG mat-file with epoched data
%   S.time - 2-element vector with start and end
