addpath - Add directories to search path

GUI Alternatives

As an alternative to the addpath function, use the Set Path dialog box.

Syntax

addpath('directory') addpath('dir','dir2','dir3' ...) addpath('dir','dir2','dir3' ...'-flag') addpath dir1 dir2 dir3 ... -flag

Description

addpath('directory') adds the specified directory to the top (also called front) of the current MATLAB search path. Use the full pathname for directory.

addpath('dir','dir2','dir3' ...) adds all the specified directories to the top of the path. Use the full pathname for each dir.

addpath('dir','dir2','dir3' ...'-flag') adds the specified directories to either the top or bottom of the path, depending on the value of flag.

flag Argument	Result
`0` or `begin`	Add specified directories to the top of the path
`1` or `end`	Add specified directories to the bottom (also called end) of the path

addpath dir1 dir2 dir3 ... -flag is the unquoted form of the syntax.

Remarks

To recursively add subdirectories of your directory in addition to the directory itself, run

addpath(genpath('directory'))

Use addpath statements in your startup.m file to use the modified path in future sessions. For details, see Automatically Modifying the Search Path at Startup in the MATLAB Desktop Tools and Development Environment documentation.

Examples

For the current path, viewed by running path,

MATLABPATH
c:\matlab\toolbox\general
c:\matlab\toolbox\ops
c:\matlab\toolbox\strfun

you can add c:/matlab/mymfiles to the front of the path by running

addpath('c:/matlab/mymfiles')

Verify that the files were added to the path by running

path

and MATLAB returns

MATLABPATH
c:\matlab\mymfiles
c:\matlab\toolbox\general
c:\matlab\toolbox\ops
c:\matlab\toolbox\strfun

You can also use genpath in conjunction with addpath to add subdirectories to the path. For example, to add /control and its subdirectories to the path, use

addpath(genpath(fullfile(matlabroot,'toolbox/control')))
