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: xval_lasso_brain_permutation_histogram.m
    path of file: ./repos/CanlabCore/CanlabCore/Visualization_functions
    
    the code of the file until where you have to start completion: function xval_lasso_brain_permutation_histogram(stats)
% Plot histograms and get permutation test-based p-value for xval_lasso_brain output structure
%
% xval_lasso_brain_permutation_histogram(stats)

create_figure('null', 2, 2);

    
function xval_lasso_brain_permutation_histogram(stats)

create_figure('null', 2, 2);

for i = 1:4
    
    h(i) = subplot(2, 2, i);
    set(h(i), 'FontSize', 24);
