genpath - Generate 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.

genpath directory returns a path string formed by recursively adding all the directories below directory. This path string does not include directories named private or directories that begin with the character @.

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.
