# MATLAB: Using packages for defining constants

automatingclassesconstantpackages

hello, using packages to define constants appears a very efficient method for repetitive defining; I was using http://uk.mathworks.com/help/matlab/matlab_oop/properties-with-constant-values.html however, classes and files are ambiguous. Will someone please indicate how a constant file may be defined and used? Also may this file be present in the local directory and may it be placed in the search path for more permanent use?
