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_qualitycheck.m
    path of file: ./repos/bspm/thirdparty/spm12/external/fieldtrip
    
    the code of the file until where you have to start completion: function [varargout] = ft_qualitycheck(cfg)

% FT_QUALITYCHECK performs a quality inspection of a given MEG/EEG dataset,
% stores (.mat), and visualizes the result (.png and .pdf).
%
% This function segments the data into 10-second pieces and performs the
% following analyses:
%  1) reads the properties of the dataset
%  2) computes the headpositions and distance covered from recording onset (CTF only)
%  3) computes the mean, max, min, and range of the signal amplitude
%  4) detects trigger events
%  5) detects jump artifacts
%  6) computes the powerspectrum
%  7) estimates the low-frequency (<2 Hz) and line noise (~50 Hz)
%
% Use as
%   [info, timelock, freq, summary, headpos] = ft_qualitycheck(cfg)
% where info contains the dataset properties, timelock the timelocked data,
% freq the powerspectra, summary the mean descriptives, and headpos the
% headpositions throughout the recording
%
% The configuration should contain:
%   cfg.dataset = a string (e.g. 'dataset.ds')
%
% The following parameters can be used:
%   cfg.analyze   = string, 'yes' or 'no' to analyze the dataset (default = 'yes')
%   cfg.savemat   = string, 'yes' or 'no' to save the analysis (default = 'yes')
%   cfg.matfile   = string, filename (e.g. 'previousoutput.mat'), preferably in combination
%                    with analyze = 'no'
%   cfg.visualize = string, 'yes' or 'no' to visualize the analysis (default = 'yes')
%   cfg.saveplot  = string, 'yes' or 'no' to save the visualization (default = 'yes')
%   cfg.linefreq  = scalar, frequency of power line (default = 50)
%   cfg.plotunit  = scalar, the length of time to be plotted in one panel (default = 3600)
