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: test_bug1447.m
    path of file: ./repos/fieldtrip/test
    
    the code of the file until where you have to start completion: function test_bug1447

% MEM 1gb
% WALLTIME 00:10:00

    
function test_bug1447

% MEM 1gb

% DATA private

% this contains the example data from Lilla, i.e. two ERPs and a layout
cd(dccnpath('/home/common/matlab/fieldtrip/data/test'))
load bug1447.mat

close all

% use a gradial mask

% match.mask(1:30,801:1800) = 1;

% select some channels and some time for masking
match.mask = zeros(59, 2200);
match.mask(1:30,801:1800) = 1;
