matlab regexp exclude specific set of file extensions

Question

I want to exclude a set of file extensions and otherwise list folder contents.

%get filenames in current directory
p = dir(pwd);
p = {p.name};
p = p(1:min(end,20))'
%construct regular expression
%exclude = {'ini','m'}; %just for your convenience
reg = '\.(^ini|m)$'; 

%actually print file names/paths of files without a certain extension
regexpi(p,reg,'match','once')

This, however, does not work. How can I get the files that exclude these file extensions (last X amount of characters in path)? I tried [^abc] but this excludes individual characters, which I don't want. Please use regexp or regexprep in your answer

keep in mind, the answer is not matlab specific (but PHP), and there may be more specific solutions. That said, yours worked perfectly =) — user2305193, Apr 13 '20 at 21:56

You wrote:

The ^ caret anchor comes after a . dot, so it will never match start-of-string. Remove it FTW:

reg = '\.(ini|m)$';
