Starting in 16a, you can use the new syntax as long as you don't specify the dimensions. In other words, the following 2 propery definitions are essentially equivalent:
classdef test
properties
prop1@uint8 = uint8(1); % undocumented way
prop2 uint8 = uint8(1); % documented way
end
end
Note that the documented dimentionality specification (e.g. (1,1) instead of scalar) requires a more recent release - it will not run on 16a. But as long as you don't specify dimentionality and as long as you are sure that the code will not be ran in 15b or earlier, then it should be perfectly safe to simply remove the @ symbol in all your class property definitions, and this code will work on any relase since 16a.
