matlabroot

The termmatlabrootcan also refer to the folder where MATLAB files are installed.

For example, in the documentation, the phrase "save tomatlabroot/toolbox/local" means save to thetoolbox/localfolder in the MATLAB root folder. If your MATLAB root folder isC:\Program Files\MATLAB\R2017b, then you would save to the folderC:\Program Files\MATLAB\R2017b\toolbox\local.

$matlabroot

The macro$matlabrootcan be used literally in some types of files to represent the full path to the MATLAB root folder.

For example, including the line$matlabroot/toolbox/local/myfile.jarinjavaclasspath.txt, adds the full path ofmyfile.jarto the static Java®class path. For more information, seeStatic Path.

Sometimes, particularly in older code examples, the term$matlabrootor$MATLABROOTis also used to represent the value returned by thematlabrootfunction.
