crawl_directories(f​ile, varargin)

This function crawls directories to search for a specific file (e.g. "MyPicture.png") or all files specified by wildcards (e.g. "*.png") and returns all found occurences as a cell array containing the full path name(s).
Additional parameters may be specified as parameter-value pairs to determine the starting directory ('path'), the search direction ('direction'), the maximum number of files to be retrieved ('n') and the maximum number of directory levels to search ('depth'). Please refer to the help for details.

Examples

files = crawl_directories('*.m', 'path','d:\Matlab','n',40); % Find at most 40 m-files starting in d:\Matlab
