MATLAB: New class object every iteration

classMATLABobjectoop

Hello. I'm trying to create new class object in every single iteration. I've founded a lot of topics how to do this with matrixes, cell arrays and many other elements, but not with object class. The idea is to creeate something like this

for i = 1:1:10
    new_obj_{i}=class_name
end

after end of the for cycle, there should be 10 objects of class_name, named: new_obj_1, new_obj_2, new_obj_3 and so on..

Is there any way how to do it?

In most cases it's better to create an array of objects. The documentations provides one way. See Construct Object Arrays. What are the pro and cons in your case?

MATLAB: How to find the names of private dynamic properties in MATLAB 7.8 (R2009a)

The ability to retrieve the names of Private Dynamic properties is not available in MATLAB R2009a.

As the name suggests, dynamic properties are dynamically added so that means that at some point in time (when you actually add the property) the name should be known. Please make sure you do not lose track of the name at that point. A way to ensure this could be to write you own superclass which keeps track of the property names and derive your class from this class instead of from dynamicprops; an example of such a super class is given below:

classdef mydynamicprops < dynamicprops
      properties (Access=private)
          % In this private property we save the names of the dynamically
          % added properties
          dynpropnames
      end
      methods
          function y=addprop(obj,pname)
              % First add the property to the list of dynamic properties
              obj.dynpropnames{end+1} = pname;
              % Then call the addprop method of dynamicprops, which actually adds the dynamic property 
              y=addprop@dynamicprops(obj,pname);
          end
          function y=GetDynamicProperties(obj)
              % Return a list of dynamic properties
              y=obj.dynpropnames;
          end
      end
end
