genpath

Generate a path string

Syntax

• genpath
  genpath directory
  p = genpath('directory')
  

Description

genpath returns a path string formed by recursively adding all the directories below matlabroot/toolbox. Empty directories are not included.

genpath directory returns a path string formed by recursively adding all the directories below directory. Empty directories are not included.

p = genpath('directory') returns the path string to variable, p.

Examples

You generate a path that includes matlabroot/toolbox/images and all directories below that with the following command:

p = genpath(fullfile(matlabroot,'toolbox','images'))

p =

• matlabroot\toolbox\images;matlabroot\toolbox\images\images;  
  matlabroot\toolbox\images\images\ja;matlabroot\toolbox\images\  
  imdemos;matlabroot\toolbox\images\imdemos\ja;
  

You can also use genpath in conjunction with addpath to add subdirectories to the path from the command line. The following example adds the /control directory and its subdirectories to the current path.
