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_timelocksimulation.m
    path of file: ./repos/spm/external/fieldtrip
    
    the code of the file until where you have to start completion: function [data] = ft_timelocksimulation(cfg)

% FT_TIMELOCKSIMULATION computes simulated data that consists of multiple trials in
% with each trial contains an event-related potential or field. Following
% construction of the time-locked signal in each trial by this function, the signals
% can be passed into FT_TIMELOCKANALYSIS to obtain the average and the variance.
%
% Use as
%   [data] = ft_timelockstatistics(cfg)
% which will return a raw data structure that resembles the output of
