What is the error you are receiving? I saved your test code to file (dummy.m) and it seemed to work.

Ok, I think the key is static methods.
Most class methods require an object as an input. That is, you could write:
function = test(obj,a)
...
end
You can call the method either as test(obj,a) or as obj.test(a) for some obj.
The exception to this are static methods. From the help file:
"Static methods are associated with a class, but not with specific instances of that class. These methods do not perform operations on individual objects of a class and, therefore, do not require an instance of the class as an input argument, like ordinary methods."
Thus, my_pi(a) works just fine, even though a is not an instance of the class, dummya.
Does this make sense?
