I have a classdef (I am not allowed to share it) to which I want to add a property that can be accessed only when explicitly called. It also needs to be dynamic. How do I go about doing it? The addprop function is not working and error says that property is not defined in the classdef

Could you elaborate on what this means? What would it mean by contrast to implicitly call a property?
The addprop function is not working and error says that property is not defined in the classdef
It would help to see copy/pastes error message.

I understand that you want to add a property that can be accessed when called and needs to be dynamic. To add a dynamic property to a class instance, the class must be a subclass of the ‘dynamicprops’ class. The properties of the ‘meta.DynamicProperty’ class correspond to property attributes. Dynamic properties are not defined in classdef blocks, but you can set their attributes by setting the ‘meta.DynamicProperty’ object properties.
Add a dynamic property to an object using the ‘addprop’ method of the dynamicprops class. The addprop method returns a ‘meta.DynamicProperty’ instance representing the new dynamic property.
