abstract class with inherite handle class

hi,

i use this code to access file of abstract class with inherited handle class I use this code .....

classdef(Abstract)  featureGenerationUnit< handles
    properties
        
        EEG;
        features;
        names;
        INFO;
        status;  
    end
    methods
        function obj = featureGenerationUnit(EEG, INFO)
            obj.EEG = EEG;
            obj.INFO = INFO;
        end
        function loadData(EEG)
            obj.EEG = EGG;
        end
        function loadInfo(INFO)
            obj.INFO = INFO;
        end
    end
    
    methods(Abstract)
        getFeatures(obj)
    end
end

i use these command to make obj but it gives error

mc = ?MyClass;
>> mc = meta.class.fromName('featureGenerationUnit');
>> fGU = featureGenerationUnit;
Not enough input arguments.

Error in featureGenerationUnit (line 12)
            obj.EEG = EEG;

other error is

fGU = featureGenerationUnit;
Error using featureGenerationUnit
The specified superclass 'handles' contains a parse error, cannot
be found on MATLAB's search path, or is shadowed by another file
with the same name.

FYI for others answering this question, I believe this other question is related.

Muhammad's comment moved here:

I use a code for preprocessing and feature Extraction and I have no code for support vector machine but i have other code which has feature is preprocessing , feature extraction and svm which is based on EEGLAB .Can I use a Code which is based on only for support vector machine without EEGLAB ?

You cannot create an instance of an abstract class. Also, your constructor expects arguments EEG and INFO, which you have not provided.
