			% Matlab example from 'Read Special System Folder Path' in the manual.
			% Slightly modified to throw more meaningful error messages and provide
			% output in char format.

			% Returns the special system folders such as "Desktop", "MyMusic" etc.
			% arg can be any one of the enum element mentioned in this link
			% http://msdn.microsoft.com/en-us/library/
			% system.environment.specialfolder.aspx
			% e.g.
			% >> getSpecialFolder('Desktop')
			%
			% ans =
			% C:\Users\jsmith\Desktop

			% Get the type of SpecialFolder enum, this is a nested enum type.

			function result = getSpecialFolderPath(nm)

			SpecialFolderType = System.Type.GetType(...
			'System.Environment+SpecialFolder');
			% Get a list of all SpecialFolder enum values
			SpecialFolders = System.Enum.GetValues(SpecialFolderType);
			sf_names = cell(SpecialFolders.Length,1);

			% SpecialFolders is not an array so cannot unwrap for in arrayfun
			ind=[];
			for i = 1:SpecialFolders.Length
			sf_names{i}=char(SpecialFolders(i));
			if strcmp(sf_names{i},nm)
			ind=i;
			% Do not stop if a match is found in order to make the full
			% list of folder names
			end
			end

			% Validate
			if isempty(ind)
			error(['Invalid folder name. Special system folder name must ', ...
			'be one of the following:', newline, strjoin(sf_names,'\n')])
			end

			% Call GetFolderPath method and return the result
			result = char(System.Environment.GetFolderPath(SpecialFolders(ind)));
