MATLAB: Removing a folder from a directory outsaide the current directory of Matlab

You just need to specify the full path of the folder you want to delete to rmdir. If you supply just the folder name, it assumes that folder is in the current directory. You can use fullfile to build the full path of the folder:

parentfolder = 'C:\somewhere\on\the\drive';
foldername = 'deleteme'
rmdir(fullfile(parentfolder, foldername), 's');
