matlab doesn't have word2pdf function. Implement your own word2pdf function like below following this link, then you can just
files = dir('*.docx');
for i=1:length(files)
file = files(i);
word2pdf(file);
end
It will convert all the word docs in the current folder into pdfs.
Your word2pdf could be a script like this:
function word2pdf(infile)
wrd = actxserver('word.application');
wrdDoc = wrd.Documents;
wrdFile = wrdDoc.Open(infile);
[fPath, fName, fExt] = fileparts(infile);
outfile = fullfile(fPath, [fName '.pdf']);
wrdFile.SaveAs2(outfile,17);
wrdDoc.Close;
wrd.Quit();
end
