path(P,['/usr/local/lib/polking']);

%% It is possible to add other directories to the path. For example, to 
%% add a directory (or folder, which is the same thing) that has mfiles
%% in it, do this:
%%
%%
%%        (1) Find the full name of the directory. One can do this
%%            by changing to the directory to be added and then typing
%%            ``pwd''.
%%        
%%        (2) Suppose that the name of the directory is 
%%                   
%%                 /home3/m308/jqp6789/my_mfiles
%%
%%
%%            To add this to the path that matlab reads, change
%%            the line above to be
%%            
%%           
%%            path(P,['/usr/local/lib/polking',...
%%                   ':/home3/m308/jqp6789/my_mfiles']);
