This package provides parallel processing on multiple cores/machines.

findfiles(varargin)
function fileCell = findfiles(varargin)
%FINDFILES  Recursively search directory for files.
%   FINDFILES returns a cell array with the file names of all files
%   in the current directory and all subdirectories.
%
%   FINDFILES(DIRNAME) returns the file names of all files in the given
%   directory and its subdirectories.
%
%   FINDFILES(DIRNAME, FILESPEC) only returns the file names matching the
%   given file specification (like '*.c' or '*.m').
%
%   FINDFILES(DIRNAME, FILESPEC, 'nonrecursive') searches only in the top
%   directory.
%
%   FINDFILES(DIRNAME, FILESPEC, EXLUDEDIR1, ...) excludes the additional
%   directories from the search.
%
%		Example:
%		fileList = findfiles('.', '*.m');
