Hi every one. As you can see in the picture at the following link I can not see properties of user defined classes in my workspace. When I type command window I can see the properties but in variable editor I can not see any thing. Is it normal, is there a way to solve this problem.

This is a reoccurring problem/request. See my previous answer for additional links. In short, the variable editor which makes use of proprietary aspects of com.mathworks.mlservices.MLArrayEditorServices. You could ask TMW to make this FOSS. You could also ask them for a product enhancement to improve the ability of the variable editor to handle custom classes (i.e., provide a hook). If you really want something like the variable editor, your best bet is to create a new method that generates a GUI and rebuild the variable editor from scratch. If you choose this road keep in mind the licensing restrictions on reverse engineering MATLAB.

This functionality was added in R2013b. I didn't see it specifically documented in the Release Notes but the changes to how structures work in the release notes is there. Here is an example.
classdef AClass
properties
A = pi;
B = [];
end
methods
function obj = AClass(B)
obj.B = B;
end
end
end
Run:
a = AClass(rand(10));
open('a')
