AMT_SUBDIR - Performs a recursive file search

Program code:

function varargout = amt_subdir(varargin)
%AMT_SUBDIR Performs a recursive file search
%
%   Usage:
%     amt_subdir
%     amt_subdir(name)
%     files = amt_subdir(...)
%
%   This function performs a recursive file search.  The input and output
%   format is identical to the dir function.
%
%   Input parameters:
%     name:   pathname or filename for search, can be absolute or relative
%             and wildcards (*) are allowed.  If ommitted, the files in the
%             current working directory and its child folders are returned    
%
%   Output parameters:
%     files:  m x 1 structure with the following fields:
%
%             '.name'    full filename
%
%             '.date'    modification date timestamp
%
%             '.bytes'   number of bytes allocated to the file
%
%             '.isdir'   1 if name is a directory; 0 if no
%
%   Example:
%     a = subdir(fullfile(matlabroot, 'toolbox', 'matlab', '.mat'))
