Can I put the filenames in a directory in a matlab vector?

In unix, this is simply: ls . > filename and then you can point to each filename with 'foreach'. Is there a complementary way to do the same thing in matlab?

fileinfo = dir();
for K = 1 : length(fileinfo)
disp(fileinfo(K).name)
end

Sorry, allow me to correct that:
fileinfo = dir();
for K = 1 : length(fileinfo)
foreach(fileinfo(K).name)
end
Where you have defined a function named "foreach" that does whatever you want done with the file. For example,
function foreach(FileName)
%take an action on the given file
disp(FileName); %action chosen was to display the file name
end
You will find, by the way, that there is no "foreach" command in Unix; you can check the Single Unix Specification at the OpenGroup.Org site.
"foreach" is, however, a command defined in some command shells, especially command shells derived from C Shell -- which is not part of the Single Unix Specification; see http://pubs.opengroup.org/onlinepubs/007904875/xrat/xcu_chap02.html

Yes, thanks. I had forgotten that 'foreach' was a shell command.

What about just doing it as a system call.
system('ls . > filename')
