26Extra comma is unnecessary in IF statement before newline.
62The variable 'p' appears to change size on every loop iteration. Consider preallocating for speed.

%GENPATH Generate recursive toolbox path.
   3 
%   P = GENPATH returns a character vector containing a path name 
   4 
%   that includes all the folders and subfolders below MATLABROOT/toolbox, 
   5 
%   including empty subfolders.
   6

   7 
%   P = GENPATH(FOLDERNAME) returns a character vector containing a path 
   8 
%   name that includes FOLDERNAME and all subfolders of FOLDERNAME, 
   9 
%   including empty subfolders.

%   NOTE 1: GENPATH will not exactly recreate the original MATLAB path.
