%FIND_LATEST_FILE find latest file in given directory and return path
|

%
|
||
% *optional input*
|
||
% path... search path; default './'
|
||
% file mask... limit results to a specific name or file
|

% EXAMPLE:
|

% out = find_latest_file;
|

% out = find_latest_file('../analysis');
|
||
% out = find_latest_file('../analysis', '*.h5');
|

% out = find_latest_file('../analysis', '*recons*.h5');
|
||
% out = find_latest_file('../analysis', {*recons*.h5, *recons*.mat});
