文末有全部图片资源

我在两年前更过如何用 MATLAB 爬取《Nature》全部插图，最近又有人问我有没有下载好的24，25年插图的压缩包，于是又去拿代码运行了一下，发现两年前写的代码今天居然还能用，代码如下：

function getNaturePNGWhileTure(YEAR)
if nargin < 1YEAR = 2024;
endpbegin = 1; ibegin = 1; jbegin = 1; 
forderName=['Year_',num2str(YEAR)];
if exist(['.\image_',forderName,'\pijbreak.mat'],'file')load(['.\image_',forderName,'\pijbreak.mat']);
end
if ~exist(['.\image_',forderName],'dir')mkdir(['.\image_',forderName]);
end
disp([pbegin,ibegin,jbegin])url_full = 'https://www.nature.com/nature/research-articles?searchType=journalSearch&sort=PubDate&year=<Y/>&page=<P/>';
url_year = strrep(url_full,'<Y/>',num2str(YEAR));options=weboptions('Timeout',inf);
html_year  = webread(strrep(url_year,'<P/>','1'),options);fprintf('1->')
A_page_num = strfind(html_year,'u-visually-hidden'); 
Z_page_num = strfind(html_year,'data-page="next"');
page_num   = html_year(A_page_num(find(A_page_num<Z_page_num,1,'last')):Z_page_num);
page_num   = page_num(32:36);
page_num   = str2double(page_num(abs(page_num)<=57&abs(page_num)>=48));for p = pbegin:page_numurl_page  = strrep(url_year,'<P/>',num2str(p));html_page = webread(url_page,options);fprintf('2\n')A_html_artical = strfind(html_page,'itemprop="name headline"');Z_html_artical = strfind(html_page,'data-track-action="view article"');for i = ibegin:length(Z_html_artical)html_artical = html_page(A_html_artical(find(A_html_artical<Z_html_artical(i),1,'last')):Z_html_artical(i));A_artical    = strfind(html_artical,'<a href=');Z_artical    = strfind(html_artical,'class="c-card__link u-link-inherit"');html_artical = html_artical(A_artical(1)+10:Z_artical);html_artical = html_artical(1:find(html_artical=='"')-1);for j = jbegin:50pbegin = p; ibegin = i ; jbegin = j;save(['.\image_',forderName,'\pijbreak.mat'],'pbegin','ibegin','jbegin')html_png=webread(['https://www.nature.com/',html_artical,'/figures/',num2str(j)]);A_png = strfind(html_png,'aria-describedby');Z_png = strfind(html_png,'alt="Fig.');if isempty(Z_png)break;elseurl_png  = html_png(A_png:Z_png(find(Z_png>A_png,1)));url_png  = ['https:',url_png(strfind(url_png,'src="')+5:end-3)];url_png  = strrep(url_png,'lw685','full');name_png = ['.\image_',forderName,'\',html_artical(10:end),' Fig-',num2str(j)];websave(name_png,url_png,options);disp(['Downloading Year-',num2str(YEAR),...'
