I have several matlab
classes declared. How could I declare constants which are seen in all classes?
For instance: these constants can be physical constants which are used in methods of all classes. The first thing coming to mind is using global variables. Is there any better way? It will be nice to declare these constants in a separate file.

A class containing the constants is a nice clean way to do this. See the article in Matlab documentation: http://www.mathworks.com/help/matlab/matlab_oop/properties-with-constant-values.html
For example, if you create a class called NamedConst
as follows:
classdef NamedConst
properties (Constant)
R = pi/180;
D = 1/NamedConst.R;
AccCode = '0145968740001110202NPQ';
RN = rand(5);
end
end
You can reference values with
radi = 45*NamedConst.R
You can find more details in the link given.
