Hello! Could anyone advise on how to write a class constructor, that accepts name-value pairs for setting properties? For the untouched properties it must use predefined values. Using like this:

X = classX('Prop1',val1,'Prop3',val3)

Thanks

With a recent Matlab version, you can do,

classdef classX
    properties
     Prop1, Prop3;   
    end
    
    methods
        function obj=classX(namedArgs)
    
            arguments
             namedArgs.Prop1=default1;
             namedArgs.Prop3=default3;
            end
            
            obj.Prop1=namedArgs.Prop1;
            obj.Prop3=namedArgs.Prop3;
        end
    end
    
end
