+help addpath
+ addpath Add folder to search path.
+ addpath FOLDERNAME prepends the specified folder to the current
+ matlabpath. Surround FOLDERNAME in quotes if the name contains a
+ space. If FOLDERNAME is a set of multiple folders separated by path
+ separators, then each of the specified folders will be added.
+
+ addpath FOLDERNAME1 FOLDERNAME2 FOLDERNAME3 ... prepends all the
+ specified folders to the path.
+
+ addpath ... -END appends the specified folders.
+ addpath ... -BEGIN prepends the specified folders.
+ addpath ... -FROZEN disables folder change detection for folders
+ being added.
+
+ Use the functional form of addpath, such as
+ addpath('folder1','folder2',...), when the folder specification is
+ a variable or string.
+
+ P = addpath(...) returns the path prior to adding the specified paths.
+
+ Examples
+ addpath c:\matlab\work
+ addpath /home/user/matlab
+ addpath /home/user/matlab:/home/user/matlab/test:
+ addpath /home/user/matlab /home/user/matlab/test
+
+ See also rmpath, pathtool, path, savepath, userpath, genpath, rehash.
